塑性应变增量 [力] plastic strain increment
- 采用合理的塑性方程,使得塑性应变增量与应力相联系;
A proper plastic formulation is used in the soil nonlinear constitutive relation, whereby plastic strain increments are related to stresses. - 从理论上说明塑性应变增量的方向不仅与应力的主方向有关,还与应力增量的方向有关。
The theoretical result shows that the direction of plastic strain increment is determined by the direction of principal stress and stress increment. - 此外,还对FLAC-3D内嵌的本构模型深入研究,塑性流动发生时塑性应变增量对应力增量的修正。
In addition, the constitutive models included in FLAC-3D are deep into research, and the stress increments are corrected in terms of the plastic strain increment while occurrence of plasticity flow.
