Inverse problem analysis for a semi-infinite solid under normal compressive load.

Abstract

This paper deals with an inverse problem analysis for a semi-infinite solid under normal compressive load. By the inverse analysis technique, the Gaussian quadrature formula is used to reduce the integral equation to a system of linear equations. Under the assumed compressive load area, the distributions of compressive loads are analyzed. Furthermore, by minimizing the square sum of compressive loads in the assumed area, the reasonable area and compressive load distributions are obtained.
