The Domain-Boundary Element Method (OBEM) for hyperelastic and elastoplastic finite deformation: axisymmetric and 2D/3D problems

摘要

This paper presents the solution of geometrically nonlinear problems in solid me- chanics by the Domain-Boundary Element Method. Because of the Total-Lagrange approach, the arising domain and boundary integrals are evaluated in the under formed configuration. Therefore, the system matrices remain unchanged during the solution procedure, and their Time-consuming computation needs to be performed only once.
