Abstract

World-wide vehicles safety experts agree that significant further reductions in fatalities and injuries can be achieved as a result of the use of new energy absorbing materials. In this field, passive safety systems still have great potential to reduce fatalities and injuries, as in the case of using new lightweight energy-absorbing materials. On this work, the authors present the development of a procedure able to perform reliable panels of sandwich sheets with metallic foam cores for industrial applications. The mathematical model used to describe the behavior of sandwich shells with metal cores form is presented and some numerical examples are included. The numerical results are validated using the experimental results obtained from the mechanical experiments. Using the crushable foam constitutive model, available on ABAQUS, a set of different mechanical tests were simulated.
