Abstract
The boundary element method is applied to damage problems by introducing convenient inelastic strains which account for strength and/or stiffness decrease. Thus, a damage parameter is not considered explicitly and the material stiffness matrix is maintained constant throughout the domain during the whole load history. As a consequence, the material remains homogeneous and a traditional boundary element approach can be followed, as well as for any other quasi-static inelastic problem (e.g., for elastic-plastic structural analysis). The main features of the technique proposed in the paper are pointed out and numerical examples are given.
