Thirdly, plasticstrainratio and strain hardening index are the two key parameters of material's formability.
塑性应变比与应变硬化指数是评价板料成形性能的两个重要参数。
2
Yield strength and ultimate tensile strength, work hardening exponent and normal anisotropy of plasticstrainratio decrease but planner anisotropy of plasticstrainratio increases.
屈服强度、抗拉强度、加工硬化指数和塑性应变比厚向各向异性降低,塑性应变比平面各向异性增大;
3
The permeability coefficient is dependent on the plastic shearing strain (ratio).
