BREAK PREDICTION METHOD BREAK PREDICTION DEVICE PROGRAM RECORDING MEDIUM AND BREAK DISCERNMENT STANDARD CALCULATION METHOD

摘要

A break prediction method according to the present invention uses the finite element method to predict the breaking of a joint of an object of analysis comprising a pair of members joined to each other and has a first step for acquiring at least the element size of a base metal part from among parameters set in an element model for the object of analysis a second step for calculating as a break discernment standard a break limit moment defined by a function including as a variable the base metal part element size and a third step for discerning whether the moment applied to the joint in a deformation analysis of the element model for the object of analysis exceeds the break limit moment and outputting the result of the discernment as a break prediction result for the joint.
