Modelling Impact Response of Sandwich Panels

Holly Barker

Abstract


Sandwich panels are a layered structure consisting of a core material between two face sheets. Sandwich panels are commonly used in aerospace and automotive industries as they combine the properties of different materials, improving the strength and durability of the structure. While sandwich panels have the combined advantage of high material stiffness and light weight, they are particularly susceptible to low velocity impact damage. This project has successfully modelled and analysed the impact response of sandwich panels using the numerical software LS-DYNA. The modelled impact response was used to determine the energy absorption capabilities of different sandwich panel materials at low velocities.
