surface yield stress的意思|示意

The calculation of micro-yield stress in surface layer and the stress-strain curves of surface layer deformation were studied.

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。

The classic plastic constitutive relation, multi-yield surface constitutive relation and over-stress viscoplastic constitutive relation are a special example of this constitutive relation.

经典塑性本构关系、多屈服面本构关系及过应力型粘塑性本构关系只是本文的特例。

Endochronic plasticity based on non-yield surface is deduced into the displacement-based finite element method and the plastic strain direct method is proposed for the plane stress problem.

介绍了位移基有限元方法 ，并在位移基有限元中嵌入了无屈服面内时本构理论 ，并提出了相应于平面应力问题的直接代入法。

In the as-quenched condition, straight slip bands and cross slip bands are shown on the surface of specimens after tensile stress has reached the yield stress;

随着时效时间的延长，拉伸断口逐渐由韧窝穿晶型向沿晶突脊型及沿晶韧窝型过渡。 在固溶状态下，当拉伸应力超过届服强度以后，出现平直滑移带及交叉滑移带；
