Boundary Emenet Formulation in Elastoplastic Stress Anaysis
AbstractThis paper presents a review of different elasto-plastic Boundary Element (BE) formulations with particular emphasis on two main approaches; the initial strain displaccmcnt- gradient approach with its modeling of the partial or full interior domain, and the particular integral approach which can be applied exclusively to the surface avoiding any modeling interior. The initial strain formulation is implemcntcd in a computer program using two-dimensional isoparametric quatratic elements to discretise either the complete intcrior domain or only the part associated with the plastic region. The BE solutions are shown to bc in good agreement with analytical and Finite Elcment (FE) solutions.
