Abstract
A break prediction method according to the present invention predicts a break of a joint portion of an object to be analyzed including a pair of members joined to each other by using a finite element method, and includes a first step of acquiring at least an element size of a base material portion, from among parameters set in an element model for the object to be analyzed; a second step of calculating, as a break discernment standard, a break limit moment defined by a function including the element size of the base material portion as a variable; and a third step of discerning whether the moment applied to the joint portion in a deformation analysis of the element model for the object to be analyzed exceeds the break limit moment, and outputting the result of the discernment as a break prediction result for the joint portion.
