Abstract
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.
1 Introduction
Analysis of non-linear problems by means of BEM can be found since the end of
seventies [l].The non-linear formulations used during a quite long time were all
based on the initial stress and strain procedures, where a constant matrix scheme
