摘要
残余应力和硬化指数的研究一直是工程界最为热点的问题之一。文中采用有限元分析软件ABAQUS进行一系列的仿真来分析硬化指数和残余应力对压痕响应的影响,得出结论:1)材料的硬化指数和残余应力对压痕响应均有影响,但硬化指数的影响比残余应力的影响大很多。2)从反演结果与输入值的对比可以看出,采用压痕法测量材料表面的残余应力是可行的。
Remaining stress and hardening of research has been a hot topic of the civil engineering field. The use of finite element analysis software ahaqus a simulation to analyze hardening index and the remaining stress response to the mark,and draws conclusion：（1） The hardening index and the remaining stress response 10 the mark. however, more than hardening of the residual influence of a lot of stress.（2） By the performance of the input values thai adopts pressing mark to measure the sarface of the material remains of stress is feasible.
