Bending life prediction method for laminated body, bending life prediction apparatus for laminated body, bending life prediction program for laminated body, and recording medium

摘要

In the method for predicting the flexion life of a laminate having a plurality of layers, for a virtual laminate, the thickness of each layer constituting the virtual laminate, the relationship between the stress and strain in each layer constituting the virtual laminate, and a flex test The stress generated in the wiring layer in the virtual laminate is calculated by using the information on the distance between the fixed plate and the movable plate in FIG. Based on the relationship between the stress and the bending life, the bending life of the virtual laminate is predicted.
