Boundary element modelling of geomaterial interfaces

Publisher Summary This chapter reviews the application of boundary element techniques to the study of non-linear processes that occur at both soil–structure and geological interfaces. Numerical schemes offer the most convenient techniques, for examining a variety of non-linear phenomena associated with separation, adhesion, friction, dilatant friction, and asperity degradation at an interface. The boundary element method can be successfully applied to examine non-linear phenomena at material interfaces. The particular advantage of the boundary element method is that interfaces on which the non-linear constraints are prescribed can be conveniently modeled through this approach. In instances where the interacting media are elastic, the interfaces are modeled as boundary constraints between regions. The versatility of the boundary element method is established by appeal to a variety of examples that deal with cracks, embedded anchor regions, and contact problems with non-linear interfaces.
