Description
SPECIFICATION
Apparatus for testing the shearing strength of test pieces
The invention relates to an apparatus for testing the shearing strength of test pieces such as welded, bonded, soldered, screwed or riveted test pieces, which can be acted upon by a shearing force in a shearing plane.
Shearing-strength tests for jointed structural members which are, for example lap-welded, riveted, screwed or bonded, are usually carried out on tensile test pieces. In this case, the ends of the test piece are gripped in a tensile-testing machine and the joint connection is exposed to a tensile force. Shearing stresses result at the joint position through the tensile force. Such a method of testing has various disadvantages, however.
Thus a tensile test piece gripped at both ends, for example, and consisting of two overlapped sheet metal parts screwed or riveted to one another will tend to bend under tension. Bonded test pieces or test pieces welded or soldered over an area also behave similarly. As a result there is a superimposition of shearing, bending and tensile stresses which is undesirable for precise determination of shearing strength and certain deformation investigations.
The present invention therefore seeks to provide an apparatus for testing the shearing strength of overlapped (welded, bonded etc.) test pieces, which avoids or substantially reduces the above described disadvantages.
According to the invention, there is provided an appartus for testing the shearing strength of jointed test pieces by acting upon them with a shearing force in a shearing plane, wherein the apparatus comprises two receiving elements for receiving the test piece, which elements can be laid against one another and are guided, by guide elements for displacements relative to each other in the direction of the shearing force with the shearing plane lying between the two receiving elements having recesses for the test piece which are so formed that, when the test piece is inserted, the test-piece cross-section to be tested lies in the shearing plane and the test piece can be supported at its ends on the receiving elements and the receiving elements have gripping heads situated opposite one another for retention in a testing machine, which heads are so disposed that a tensile and/or compressive force exerted by the testing machine acts as a pure shearing force in the shearing plane.
The apparatus according to the invention is of such a nature that it can itself be gripped in the testing machine and transmits forces to the test piece which can produce both static and dynamic shearing stresses, that is to say shearing stresses varying in magnitude and possibly also in direction. Thus, apart from static shearing-strength tests for example, dynamic shearing-strength tests can also be carried out on joint connections by regulation of force or travel. With appropriate construction of the apparatus according to the invention, the fatigue strength of screw nuts and screw locking means can also be tested.
The invention will now be described in greater detail, by way of example, with reference to the drawings, in which:
Figure 1 shows a longitudinal section through an apparatus according to the invention, illustrated diagrammatically;
Figure 2 shows a cross-section through the apparatus shown in Figure 1, with a sliding or roller guide;
Figure 3 shows a cross-section through an apparatus according to the invention with a dovetail guide.
The apparatus shown in Figure 1 comprises two receiving elements 1,2 for the test piece, which can be applied against one another and which can slide on one another. They are guided by guide elements 3,4 which are only indicated diagrammatically in Figure 1, in the direction of the shearing force which is designated by double arrow S. The guide elements 3,4 can be so constructed that guiding transversely to the direction of the shearing force S is additionally achieved. Gripping heads 5,6 for enabling gripping of the apparatus in a testing machine are provided on the receiving elements 1,2.
The receiving elements 1,2 have recesses 7,8 in which inserts 9,10 are received. The inserts 9,10 are connected to the receiving elements 1,2 in a suitable manner, for example by screw connections, in which case the screwing can be effected not only from the inside but also from the outside of the receiving elements. In their external dimensions, the inserts 9,10 may correspond to the size of the recesses 7,8. They may, however, also be smaller than the recesses (as illustrated in Figure 1). Furthermore, they may also be of frame-shaped construction of suitable form. The inserts 9,10 may be also formed that different test pieces can be received, while the external dimensions of the inserts may be the same. Their internal shape may be adapted to different sizes and shapes of test pieces.
Inserted in the inserts 9,10 are sheet-metal distance pieces 11,12 which with a jointed test piece 13, which consists, for example, of two sheets of metal bonded together, can be adjusted in their position in relation the the shearing plane SE.
Apart from the sheet-metal distance pieces, additional supporting plates may be present for the adjustment of the test piece (see also Figure 3). At the ends, that is to say in the direction of the shearing force S, the test piece is supported on the inserts 9,10 and via these on the receiving elements 1,2. The end faces of the test piece, which transmit the sharing forces, are so constructed and machined that a satisfactory transmission of force is ensured from the receiving elements 1,2 or the inserts 9,10 to the test piece.
The guide elements, which are only indicated in
Figure 1, may be constructed in very different ways. Together with the receiving elements 1,2 the guide elements should be so formed that the ele ments can slide on each other with as little play as possible. Two simple embodiments are illustrated in Figure 2. Other forms of the guide elements are, however, also possible.
Figure 2 shows a cross-section through the apparatus shown in Figure 1, wherein a sliding guide for the receiving elements 1,2 is illustrated on the left-hand side of the Figure and a roller guide on the right-hand side. In the case of the sliding guide, the receiving elements 1,2 and the guide elements 3 comprise sliding surfaces G on which they can slide on one another. The sliding surfaces may consist of a material with particular favourable frictional behaviour, for example Teflon (RTM).
Instead of the sliding surfaces, sliding elements may also be provided, as indicated at GE, which may be connected to the receiving elements or to the guide elements.
In the case of the roller guide, rollers, for exam ple roller cages R, are disposed between the receiving elements 1,2 or between receiving elements and guide elements 4, as a result of which a particularly easy displaceability of the receiving elements in relation to one another is possible.
In the case of the guides illustrated, after the two receiving elements 1,2 have been joined together, the guide elements 3,4 are secured to one receiving element, to the receiving element 1 in the example illustrated, for example by screws. The length of the guide elements, of the sliding surfaces or of the roller elements is selected appropriately to the purpose. For example, the guide elements may be somewhat shorter than the sides of the receiving elements situated opposite one another. It is also possible to provide guide elements only at the two ends of the receiving elements.
Combinations of sliding and roller guides may also be provided to guide the receiving elements.
Figure 3 shows a cross-section through an apparatus according to the invention wherein a sliding slide in the form of a dovetail guide 14 is illustrated between the two receiving elements 1,2. If a dovetail guide is used, care must be taken to ensure that the two receiving elements 1,2 can be mounted or connected together with the test piece 13 inserted. For this purpose, the receiving element 2 may have an opening 7' (indicated in Figure 1 in broken line) passing right through the element.
Thus it is possible to push the receiving element 2 over the insert 9 with the test piece 13 already inserted during the joining together in the dovetail guide. The insert 9 can then be screwed to the receiving element 2 from the outside. In this case, the screw connection takes up the test forces.
The dovetail guide on the receiving elements 1,2 may also be provided with discontinuities which fit one another so that the two receiving elements can be placed one on the other with the piece inserted.
Then they are displaced in relation to one another into the testing position, during which the guides of the receiving elements again engage in one another. In this case, the position of the test piece in the receiving elements must be appropriately fixed.
The receiving elements 1,2 and the inserts 9,10 must be so shaped that the necessary displacement path of the receiving elements is ensured.
For example, the inserts 9,10 may be open at one side (for example in the form of a frame). With this construction of the guide elements, however, testing forces can normally only be applied in one direction of force.
Figure 3 also shows different constructions of the inserts 9,10 of the supporting plates or testpiece supports 16,17 and of the sheet-metal distance pieces 11,12 for the test piece 13 in comparison with the illustration in Figures 1 and 2.
As a result of suitable construction of the testpiece supports 16,17 (Figure 3) and possibly of the inserts 9,10, screw and rivet connections can also be tested. In this case, projecting screw and rivet heads are received in recesses in the test-piece supports. The supporting plates 16,17 may also be so constructed that they can be adjusted or screwed from the outside of the receiving elements 1,2.
For the application of shearing stresses with alternating directions of force, the test pieces must be supported at the ends in both receiving elements in both directions of force, as illustrated with the inserts 9,10 in Figure 1 for example. For this purpose, it is also possible to provide a suitable opening, which is disposed parallel or perpendicular to the shearing plane, in an least one receiving element. In Figure 2, an opening perpendicular to the shearing plane is indicated by 18' and in Figure 3 one parallel to the shearing plane is indicated by 18. Supporting elements to support the test piece at the ends or inserts to receive and support the test piece may be inserted through these openings.After the joining together of the receiving elements 1,2, the supporting elements or inserts are connected without play to the receiving element in which the opening is provided, for example being screwed or wedged. The test piece can also be supported at both ends in both receiving elements in this manner.
The arrangement with an opening in at least one receiving element can be used, for example, with a dovetail guide. Furthermore, with such an arrangement, it is possible to connect the guide elements rigidly to the receiving elements. If the opening in at least one receiving element is sufficiently large, the whole test piece can also be inserted into the apparatus with the receiving elements previously mounted, that is to say already joined together. In this case, it is also possible to provide openings situated opposite one another (symetrical to the shearing plane) perpendicular or parallel to the shearing plane, in both receiving elements.
For certain tests, damping elements, for example in the form of leaf-spring elements, may be inserted at the end supporting points of the test pieces. For precise measurements of force, travel and deformation, additional pick-ups, for example wire strain gauges may be fastened to the shearing test piece.
Compression joints and snap connections such as are used, in particular, for plastics structural members, as well as clip on connections, can also be tested or subjected to a shearing stress with the apparatus according to the invention.
In order to carry out a shear test, the jointed test piece 13 is inserted in one receiving element 1,2 and the second receiving element 2,1 is displaceably mounted on the first. If at least one receiving element comprises an appropriate opening 18,18', the test piece can alternatively be inserted with the apparatus already assembled. The apparatus, with the test piece in place, is then gripped in a testing machine at the gripping heads 5,6 and subjected to tensile and/or compressive stress so that the required shearing force is transmitted to the test piece 13 via the inserts 9,10 or other suitable supporting elements. In the course of this, not only static but also dynamic loading, for example repetitive stress or stress with an alternating direction of force, is possible.
