Constitutive Laws for Dynamic Modelling of Soils,

Abstract

Soils are composed of a combination of solid particles, water, and often, air. The constitutive behavior of water and air are fairly well understood. Attention in this study is given only to the mechanical behavior of the soil skeleton under isothermal conditions. Characteristics which should be displayed by any soil models used under generalized loading conditions are enumerated. A summary of existing models are discussed--Elastic and Viscoelastic Models, One-Dimensional Curve Fits, Ideal Elasto-Plasticity, Elastic Non-Ideally Plastic Models, Endochronic Models, The Failure-Seeking Model, as well as comparison of existing models with desired features. Recommended lines for advancement in generating a more universal model are also included. (Author)
