A BEM implicit formulation applied to damage mechanics models

摘要

In this work, the implicit BEM formulation, initially developed in the context of plasticity analysis is extended to incorporate damage mechanics models. The algebraic equations adopted for the formulation are obtained either using displacement or traction equations, for the boundary nodes, and stress (or strain) equations for the internal nodes. The consistent tangent operator has been obtained for situations: the conventional non-linear BEM system of equations.
