Abstract

Cuando se efectúa un análisis dividiendo un objeto de análisis en varios fragmentos, dos elementos adyacentes son combinados después del análisis o bien el análisis es efectuado utilizando dos tamaños de los elementos divididos con el objeto de comparar la proporción de reducción de espesor de placa o la distorsión principal máxima en la misma posición que incluye el mismo elemento. El elemento que presenta una diferencia grande como resultado de la comparación es extraído como región de peligro de ruptura. Con esta configuración es posible extraer con seguridad una porción de peligro de ruptura cuando se predice una ruptura por el método de elementos finitos.
