The variation is smaller in plastic relaxation than the elastic one under the same in-plane strain.
在相同的平面应变下，塑性弛豫引起的电荷分布不均匀性变化小于弹性变形。
Secondly, a plastic relaxation function describing the behaviour of plastic flow under high temperature and high pressure is suggested from the viewpoint of dislocation dynamics.
其次，从位错动力学角度建议了一个塑性松弛函数以便描述高温、高压下塑性流动的特性。
Used for testing indexes of polyurethane monofilament, such as breaking tenacity, elongation at break, load at specified elongation, relaxation of stress, plastic deformation, etc.
用于测定氨纶丝断裂强度、断裂伸长率、定伸长负荷、应力松弛，塑性变形等性能指标。
