Description	The contribution is focused on finite element simulation of dynamic response of sandwich plate loaded by transverse low-velocity impact. The model is capable to describe non-linear orthotropic elastic behavior and damage of skins and elasto-plastic behavior of the core foam. The identification of material parameters of laminated textile fiber-glass composite skin and polyurethane foam core was performed using combination of gradient optimization method and finite element simulations. Experiments, static tensile and compressive tests, were performed separately for skin and core and averaged force-displacement curves were used as target functions for identification process. User defined material model for composite skin was implemented into Abaqus software using umat subroutine. Strengths of materials in material axes directions were determined directly from the experimental results. Static three-point bending tests of sandwich beam were performed in order to validate obtained data from the static tests.
