Analysis of Stress and Strain Distributions in Triaxial Tests Using the Method of Finite Elements.

Abstract

A finite element computer code called WESTES was developed to study the influences of laboratory testing equipment on the states of stress and strain induced in cylindrical specimens of earth media. The code can solve general static, axisymmetric, boundary value problems and is programmed to take an incremental, nonlinear constitutive model called the Variable Moduli Model II. Some of the special features of the code include the ability to simulate cyclic (load/unload/reload) laboratory tests using iterative treatments at the load/unload and unload/reload interfaces and special logic to separately handle loading and unloading in the volumetric and deviatoric stress components as dictated by the constitutive model.
