DAMAGE EVALUATION METHOD BASED ON HEAT GENERATION CHARACTERISTICS OF STEEL UNDER CYCLIC BENDING STRESS

Abstract

This paper discusses a basic proposal and investigation of a damage evaluation method for steel members by temperature measurement. Dynamic cyclic loading tests were conducted on specimens simulating steel members subjected to cyclic bending stress, and the temperatures of various parts of the specimens were measured to confirm the applicability of the proposed damage evaluation method. As a result of the experiment, it was confirmed that the damage evaluation based on the temperature measurement agreed with the damage degree estimated from the history of load and deformation.
