Abstract

Boundary integral equations are formulated by associating in a Betti equation the real elastic state and a fictitious state generated by distributions of static and kinematic discontinuities and of inelastic strains. A suitable discretization is adopted for all variable fields and plastic constitutive laws are enforced in an average sense. Thus a symmetric formulation of the direct BEM is obtained.
