Abstract

The metal foams are materials with great potential for use in various fields of industry. The pores created deliberately in the structure give them many exceptional properties; one of the most important features is the ability of energy absorption. In the experimental part the castings of metal foam with a regular internal structure were manufactured by simple foundry way (infiltration of metal into the cavity of the mold is filled preform). The samples made from porous material were subsequently tested in mechanical testing. For a comparison of experimental data 3D math ideal model (model with perfectly smooth wall) was created. The initial model was calculated by using an explicit dynamics, which is primarily used in areas of extreme deformation with a small increment of time, e.g. car crash tests. The based on these results it is concluded the opinion, whether it is a convenient time to continue in the optimization of metal walls on the way of simulation or it will be necessary to continue with creating of physical models and experiments.
