PROBLEM TO BE SOLVED: To appropriately reflect the effect of plastic deformation (work hardening) that occurs during machining on CAE analysis. SOLUTION: An apparatus for CAE analysis, which, for a subject of analysis including metallic parts manufactured from a metallic plate through machining, conducts nonlinear analysis using a finite element model of the subject of analysis on its behavior involving plastic deformation under preset analysis conditions, calculates plastic strain of the machined part of the finite element model using parameters about an angle formed between adjacent elements, the plate thickness of each element and the size of each element, as a pretreatment prior to the nonlinear analysis, for each element corresponding to at least the machined part of the finite element model. The plastic strain calculated is reflected on the initial state of the finite element model. COPYRIGHT: (C)2007,JPO&INPIT
