hydrostatic stress

In this paper, the formulas of the maximum tidal shear stress and the tidal hydrostatic stress for shallow earthquake are obtained from the tidal stress tensor. the relationship of their phases are discussed.

本文从潮汐应力张量出发，求出浅源地震的日月潮汐最大剪切应力和流体静应力的表达式，讨论了它们位相间的关系。

The Duncan-Chang E-B model is used to simulate the non-linear mechanical behavior of soil. With the separation of hydrostatic stress and stress deviator, a partial derivative formulation about displacement and parameter is derived in finite element evaluation.

以能较好模拟土体非线性力学行为的Duncan-Chang E-B模型为基础，通过分解应力球量与应力偏量，导出一个在有限元计算中，位移对参数偏导数的数值计算公式。

The new theories include a tension stress theory of the rigid-plastic mechanical model when H/ D> 1 and a shearing stress theory of the hydrostatic stress mechanical model when H/ D < 1.
