A simplified kinematic hardening plasticity framework for the constitutive modelling of soils is presented. In contrast to conventional kinematic hardening plasticity, the yield surfaces do not enter explicitly into the governing equations but are used only for the purpose of computing an effective hardening modulus. This leads to models reminiscent of conventional nonlinear elastic/perfectly plastic models, thus facilitating an efficient numerical implementation. The framework is detailed both with respect to total and effective stress analysis. Its capabilities are illustrated by the development of a simple model for undrained total stress analysis of clays.

用于土壤本构建模的简化运动硬化塑性框架

介绍了用于土壤本构建模的简化运动学硬化塑性框架。与传统的运动硬化塑性相比，屈服面没有明确地进入控制方程，而仅用于计算有效硬化模量的目的。这导致模型让人想起传统的非线性弹性/完美塑性模型，从而促进有效的数值实现。该框架在总应力分析和有效应力分析方面都有详细说明。它的能力通过开发用于粘土不排水总应力分析的简单模型来说明。
