THE APPLICATION OF THE VISIOPLASTICITY METHOD TO SOFT-SOIL MOBILITY PROBLEMS

Abstract

The visioplasticity method of analysis, employed extensively in investigations related to metal processing problems, is applied to an analysis of a rigid wheel traversing a soft soil where flow is confined to two dimensions. Emphasis is placed on the way data taken from X-ray photographs are reduced in order to obtain the velocity, strain-rate and strain patterns for this flow condition. Consideration is given to modeling the dominant constitutive or material behavior and how this is incorporated along with the governing continuum field equations to provide calculations of the energy dissipation rate and the stresses acting on the wheel.
