POSSIBLE EFFECTS OF SERVICE CHANGES IN COMPRESSION STRESS-STRAIN CURVES ON BUCKLING,

Abstract

In work-hardened engineering materials, the proportional limit stress in compression is seriously reduced after fatigue; coonsequently, the fatigue of structures gives rise to a lowering in strength of the compressed parts. In order to draw attention to this fact, a short review and some numerical calculations are made on problems of buckling in the plastic range with initial eccentricities which are possibly modified by creep and show fatigue changes in plastic properties.
