Abstract

The Dual Boundary Element Method commonly used for the modelling of crack problems in metals is applied in this paper to a geomechanics problem involving natural material, i.e. rock. The example chosen is from earthquake control theory. The technique involves defining a new interpolation scheme for continuous elements which incorporate certain continuity conditions arising from the hypersingular nature of the integrals involved. An integration technique based on the singularity subtraction method using series expansions is adopted for the hypersingular integrals, and in order to produce a reliable numerical method the dual equations are cast in a suitable form. 1. Introduction Boundary element methods have enjoyed considerable success in the area of ge- ome
