stress-strain hardening的意思|示意

The stress-stain curve shows the strain-hardening characteristic without initial shear stress.

当不存在初始剪应力时，应力–应变关系表现为硬化型曲线；

Power law model can describe both strain-hardening and strain-softening behaviors, which can be used effectively to model stress-strain relationship of coarse-grained materials.

幂律模型既能反映硬化特性又能模拟双曲线模型不能反映的应变软化关系，因而能合理地反映粗粒料的应力应变关系。

This paper pressents a polynomial with four odd terms to fit the stress-strain relation for the materials with arbitrary hardening behaviour in the region of small elastoplastic deformation.

首先在小弹塑性范围内用应变的奇次四项式相当精确地拟合一般硬化材料的拉伸曲线；

When the stree strain relationship is the weak hardening, the relationship between stress ratio and strain incremental ratio shows the straight line with two different slopes.

当材料的应力应变关系为弱硬化型时，应力比与应变增量比关系为两段斜率不同的直线；

The elastic range, the plastic range (during which the material flows at a constant stress), the strain-hardening range, and the range during which necking occurs, terminating in fracture.

弹性范围，塑料范围（当材料以不变的应力流动时），应变硬化范围和发生颈缩现象以其断裂终止的范围。

The deformation and stress condition of the micro-composite are studied according to the shear-lag theory and strain-hardening law.

按照剪切滞后理论和应变硬化规律，研究微复合材料的变形和应力状态。
