Abstract:This thesis represents a mixed computational formulation of Finite Element, Finite Difference and Boundary Element Methods for solving problems of finite strain elastoplasticity in 3D. For geometrical nonlinearity the Total Lagrangian Formulation and for material nonlinearity the Multiplicative Formulation have been selected. The variational formulation which leads to multidimensional singular integrals has been discretisied. The final nonlinear system of equations has been solved by the Newton-Raphson method. The system is programmed in Fortran. The results are visualized by the Matlab software and compared to analytical solutions and Finite Element methods.
