| 摘 要： | 介绍了三轴条件下的两个三模量增量非线性应力-应变关系式。 其中一个用 K , G, J 表述的关系式便于常规有限元计算使用。在次弹性理论基础上将三轴条件下的用 K , G , J 表达的三模量关系式推广到一般的三维应力条件下。给出了三维本构关系的张量形式和矩阵形式, 并对矩阵形式中典型项目的物理意义作了解释。

| Abstract: | This paper introduces two three-moduli incremental
non-linear stress-strain relationships under triaxial stress condition. The relationship
using is useful for finite
element implementation. Based on hypoelasticity, this relationshiop is generalized into a
three-dimensional stress-strain relationship. Both tensor form and matrix form are given.
The physical meaning of the typical items in the matrix form is explaned. |
