Abstract

The boundary integral equations constitute a remarkably elegant formal solution of the elastoplastic problem of unsaturated expansive soils. Numerical techniques (Boundary element method) must be employed to solve them. The main difficulty of this nonlinear analysis is that the boundary integral equations are augmented by a domain integrals involving initial stresses which necessitate domain discretization and the specification of interior cells in the parts of the domain that are likely to yield (unlike the linear case which involve only the boundary discretization). The main purpose of this paper is to write the discretized form of boundary integral equations of expansive soils using the shape functions.
