FEM Analysis of Sandwich Shells with Metallic Foam Cores
Traffic-related accidents are a major threat to life in the European Union, plus all the associated social and economic costs, remain unacceptable. It is generally considered that the number of traffic-related accidents is an unacceptable high burden for Europe´s society and economy. 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. The main goal of this project is the development and evaluation of an innovative system able to perform reliable panels of sandwich sheets with metallic foam cores for industrial applications, especially in automotive and aeronautical industries. In this work, we first made an approach to analyze sandwich shells with metal cores forms. To this end we used a numerical model based on the finite element method using commercial software ABAQUS.
