摘要

实验表明

经典塑性力学难以反映岩土材料的变形机制

究其原因在于经典塑性力学作了传统塑性势假设、关联流动法则假设和不考虑应力主轴旋转的假设。广义塑性力学放弃了这些假设

采用了分量理论

由固体力学原理直接导出塑性公式

它既适用于岩土材料

也适用于金属。

Abstract

Experiments show that the classic plastic mechanics fails to reflect the real deformation mechanism of geomaterials because the classic plastic mechanics is based on the hypothesis of the traditional potential theory

the hypothesis of the associated flow rule and the hypothesis of not considering rotation of stress principal axes. The generalized plastic mechanics gives up all these hypo theses and gets all its plastic formulas from solid mechanics directly

so it ca n be used for both geomaterial and metal.
