Abstract: Hyperelastic material model based on the logarithmic description is implemented in the finite element code. Procedure for the calculation of all the necessery quantities at the Gaussintegration points is described in details. The second-rank update BFGS solver is used to process the governing equilibrium equations. The solution algorithm is then combined with the prediscretization contact search method in order to include contact boundary conditions. As an example, numerical simulation of the compression test of a rubber cylindrical specimen is presented.
Keywords: BFGS method; hyperelasticity
