Soil Model Evaluation under Dynamic Loadings,

Abstract

Many different types of constitutive relationships are available for calculating the response of geologic media to impulsive loading. Choosing a material model which is suitable for a particular situation can be difficult. Model selection is often based on personal experience of the calculator, and this may or may not result in optimum efficiency and response. This paper describes a computer code which has been developed as an aid for studying material constitutive models. The Soil Element Model (SEM) can calculate the response of a given material model to laboratory and in-situ test conditions, arbitrary strain paths, or one-dimensional wave propagation. It is useful for developing models, performing parametric studies to determine model component influence, and comparing model behaviors. A study is presented which illustrates the use of this code to compare the ability of several material models to replicate laboratory and in-situ data. The study focuses on sand from a site near Yuma, Arizona, and examines the advantages and disadvantages of each model selected. (Author)
