STUDY ON SHAKEDOWN OF STRUCTURES UNDER DIFFERENT STRAIN-HARDENING MODELS
不同应变强化模型下结构安定性的研究

It is important in engineering applications to study the shakedown of structures under loads changing with time. The shakedown of structures is related to the strain-hardening models of materials used. The present paper considers the shakedown problems of structures under several strain-hardening models. The shakedown conditions of kinematic-hardening and mixed -hardening structures are given. The conclusions obtained here simplify the shakedown analysis of strain-hardening structures.
