Abstract
A new approach is outlined for dual BEM formulation for elastoplasticity, which exploits certain features of the constitutive relationships involved. By the use of a quadratic orthotropic yield criterion with strain hardening, the unknown non-linear terms, as the initial strains, are now defined in function of the scalar flow factors. Dual BEM variable stiffness formulation, based on the utilisation of the traction equation on one of the crack surfaces and the displacement equation on the other, is presented for the solution of general elastoplastic fracture mechanics problems.
