SIMPLE EVALUATION METHOD FOR INELASTIC DEFORMATION

摘要

PROBLEM TO BE SOLVED: To provide a simple evaluation method for an inelastic deformation in which an aged inelastic deformation can be evaluated quickly and which can be reflected to the low cost of a product by lowering a design cost.;SOLUTION: The inelastic deformation after many hours' use is evaluated simply on the basis of the evaluation of a strength-of-materials-based elastic stress and evaluation and on the basis of creep speed constructive mood data at a test piece level.;COPYRIGHT: (C)2003,JPO
