Numerical Simulation of the Impact on Wide Composite Sandwich Beam

Abstract:

This paper is focused on the development of a finite element model describing the behaviour of sandwich structure with composite skins and low density foam core in case of low-velocity transverse impact load. The material properties of foam core and composite skins were determined using tensile tests. The non-linear elastic behaviour of composite skins was implemented into the commercial finite elements software using material subroutine. The identification process combining finite element simulations and mathematical optimization method was used for the determination of material parameters of the composite skins. The foam core was modelled using Abaqus Low-density Foam material model considering the non-linear behaviour in case of tension.
