摘要
本文对表面微观屈服应力的测量与计算方法及表面变形的应力应变曲线进行了分析研究。结果表明:表面微观屈服应力与加载方式有关;表面变形的应力应变曲线具有双线性特征。
The calculation of micro-yield stress in surface layer and the stress-strain curves of surface layer deformation were studied. The results show that the micro - yield stress in surface layer is related to looding method and the stress-strain curve has a double linear character.
