加载历史对循环硬化的影响

THE EFFECT OF LOADING HISTORY ON CYCLIC HARDENING

  • 摘要: 本文研究了45#钢和LY-12CZ铝合金在室温条件下拉扭复合比例及非比例加载时的循环硬化特性,其结果表明不同加载路径循环硬化程度不同,纯扭硬化程度最小,圆形路径硬化程度最大。着重研究了不同循环历史对后面循环稳定应力幅值的影响。

     

    Abstract: In this paper, the cyclic hardening behavior of 45 # steel and LY-12CZ aluminum alloy under proportional and non-proportional combined loadings of tension and torsion at normal room temperature has been investigated.The experimental results show that the cyclic hardening levels are different for different loading paths. The least is for the pure torsion, while the highest is for the circular path. The authors have especially investigated the effect of different cyclic history on the amplitudes of stabilized...
