摘要: Boundary integral equations are formulated by associating in a Betti equation the real elastic state and fictitious generated distributions of static kinematic discontinuities inelastic strains. A suitable discretization is adopted for all variable fields plastic constitutive laws enforced an average sense. Thus symmetric formulation direct BEM obtained. For finite-step problem backward-difference (stepwise holonomic) sense solved iterative procedure extremum convergence theorem given. An implementation some aspects computational experience achieved briefly summarized.
