THERMAL STRESS ANALYSIS SIMULATION PROGRAM AND ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a simulation program and an analysis method for performing a thermal stress analysis of a variety of alloys to be obtained with high accuracy within a wide temperature range from a high temperature zone immediately after solidification to a room temperature without largely depending on alloy species.;SOLUTION: A total distortion is given by adding a plastic strain to an elastic strain following a Hooke's law with respect to the stress. The plastic strain is given from a relationship in which the stress is proportional to a value obtained by raising a strain rate and multiplying it by an internal valuable S. The internal valuable is given from a hyperbolic function which regulates a shape of a strain-non elastic strain curve of the alloy.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
