塑性形变 [力] plastic deformation
- 塑性形变压力是岩石由弹性状态转变为塑性状态所产生的压力。
Plastic deformation pressure is the pressure caused by changing the status of rock from elasticity into plasticity. - 在提高温度的情况下,金属的性能取决于形变率, 塑性形变是通过各种晶界的滑移来实现的。
At elevated temperatures, and in materials whose properties depend on the deformation rate, plastic deformation also takes place by means of grain-boundary sliding. - 冷却过程的应力和冲击热应力也将导致材料发生塑性形变,其作用范围超过了热影响区。
The shock stress wave and the stresses associated with cooling can also lead to plastic deformations, and their affected depth extends far beyond the heat-affected zone.
