A User's Guide for BIE3D - A Boundary Integral Equation Computer Program for Three-Dimensional Elastostatic Analysis.

Abstract

This Memorandum describes a three dimensional numerical stress analysis computer program which is based on the Boundary Integral Equation (BIE) method and is used to carry out stress analysis of three dimensional components of complex geometry. Stress intensity factors can be derived for the case where the component is cracked. The body is assumed to have linear elastic isotropic properties. The condition of plane strain is assumed at all points along the crack front except where it intersects the free surface, where plane stress assumptions are made. The program is written in standard FORTRAN and it is now operational on the Materials and Structures departmental VAX computer. Step-by-step instructions have been presented together with examples illustrating the input and output formats. Validation and accuracy checks of the computer program have been made by solving two bench mark problems where the BIE solutions are compared with known accurate solutions. Keywords: Great Britain; Boundary element method; Boundary integral equations; Three dimensional.
