Abstract

Ensuring that the heat generation by plastic deformation corresponded to the increasing of its plastic strain energy, the behaviors of the heat distribution of SUS304 which had anisotropy under deformation and fracture was examined by using a thermal image camera with two dimensional array sensors. Furthermore FEM elasto-plastic analysis coupled with heat generation and transient heat conditions was performed. It was shown that the analytical results showed good agreement to the experimental ones, and we could evaluate the anisotropic influence of the material in the plastic deformation and the fracture process as a thermal image distribution macroscopically. 1 Introduction The failure of mechanical members largely depends on the size and the development of plastic deforma
