Numerical Methods for Creep Analysis in Geotechnical Problems.

Abstract

This report presents the results of a theoretical study of inelastic material behaviour produced by static loading on a viscous continuum. A number of issues are addressed in an attempt to introduce inelastic behaviour into piecewise numerical methods. Methods based on similitude and direct integration of the displacement field are investigated. Potential field theory is invoked as a means of describing stress distributions which are assumed invariant with respect to time of straining the material. No attempt has been made to include forced flow, strain hardening or frictional material properties. The analysis is restricted to slow deformations and results in a line integral for conversion of strain rate to displacement as a function of time of straining. The interpretation of experimental data is viewed from the stand-point of functional analysis as it is felt that this branch of mathematics has unexplored implications in the study of creep of deformable bodies.
