Resources are limited! Therefore a responsible handling is obligatory. This is one of the main reasons green engineering is so popular nowadays. Light weight construction is one possibility to save energy and resources. Reduction of weight can either be achieved by using materials with small masses like aluminum or ucould be achieved by adopting porous structures, which additionally reduce the consumption of resources. There exist porous structures with an average density reduction of over 90 percent, while many material properties remain preserved. Those materials are often used in safety engineering as energy absorbing devices. Analyzing the material properties of such porous structures, e.g. tensile strength and shear strength, is the main aim of the present Molecular Dynamics (MD) simulations. All simulations are performed on the high performance cluster of the computation center HLRS at the University of Stuttgart. The applied simulation package IMD (ITAP Molecular Dynamics) [1] is customized for such massive parallel simulations. This tremendous calculation power together with the application to particles with reduced average density leads to the possibility of simulating larger materials systems as compared to the case of dense materials.
