岩土类工程材料的蛋形屈服函数

Egg Shaped Yield Function for Geotechnical Engineering Materials

针对岩土类材料,提出了一种蛋形屈服函数,并在此基础上写出了能够包含迄今常见屈服函数形式的表达式。给出了确定参数的方法及本构方程。

An egg shaped yield function characterize yield surface for geotechnical materials is suggested. Based on the function, a generalized formulation that can include common different yield functions have been developed. Methods used to determine the parameters of the function and the constitution equation are given.
