    This paper is focused on a progressive failure analysis of a sandwich composite panel considering a non-linear model of core and skins using explicit analysis. The material properties were determined ... from tensile and compressive tests of the outer composite skin and the foam core. A user-defined material model was used to describe the non-linear orthotropic elastic behaviour of the composite skin. The material parameters of the outer composite skin were determined using the identification process performed using a combination of optimization method and finite-element simulation. The Low-Density Foam material model was used for the foam core. The obtained material data were validated using a three-point bending test of a sandwich beam.
