The scope of this paper is to have an alternative to the use of an explicit plastic potential in elastoplastic models for soils. This is possible through the definition of a stress–dilatancy relationship and a simple expression for an auxiliary surface in lieu of a given expression of the plastic potential surface. This approach results in a flexible definition of the model and to very simple expressions of the auxiliary plastic potential derivatives.

土壤弹塑性的辅助塑性势法

本文的范围是在土壤弹塑性模型中使用显式塑性势的替代方法。这可以通过定义应力-剪胀关系和一个简单的辅助表面表达式来代替给定的塑性势表面表达式。这种方法导致模型的灵活定义和辅助塑性势导数的非常简单的表达。
