Análise de grandes deformações e plasticidade por meio de elementos finitos isoparamétricos

Through the finite element method, the non-linear behavior of problems involving large deformation and plasticity is analysed. Both for Lagrangian and Eulerian formulation, the continuous is approximated by quadratic isoparametric elements, and the analysis of plane stress, plane strain and revolution solids is effected. For the solution of surface structural problems, such as plates and shells, quadratic tridimensional elements were degenerated and quite satisfactory results were obtained with this procedure. The solutions to various examples are discussed and compared, and certain conclusions are presented.
