PREDICTING METHOD OF STRESS OCCURRING IN STRESS CONCENTRATION PART IN RESIN MOLDED ARTICLE HAVING STRESS-CONCENTRATING SECTION, AND CREEP RUPTURE LIFETIME PREDICTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of predicting how much stress is produced in a stress-concentrating section and in what time interval, even for a resin-molded article having the stress concentration part breaks, when a certain load is applied to it.;SOLUTION: This prediction method determines the correlation between analysis stress in the stress-concentrating section determined by analysis, when a predetermined fixed load is charged on the resin molded article having a geometrical stress-concentrating section and a correction coefficient for making the analysis stress in a predetermined breaking period approach the analysis stress, in a resin test piece that does not have geometrical stress-concentrating section during a similar breaking period.;COPYRIGHT: (C)2011,JPO&INPIT
