Influence of the Microstructure of Metal Foams on Macroscale

Volume element of metalic foam

Metal foams and their applications are of increasing interest in the area of research and development. High stiffness in conjunction with low density, high percentage of free surface within the volume, capacity of high energy absorbation and good damping properties of metal foams are relevant for light weight construction, chemical reactions, crash elements and vibration damping. Metal foams are used for example as car body elements, crash absorbers, fast moving vibrating devices, heat exchangers, catalysts, heat shieldings.

In dynamic applications it is necessary to describe eigenfrequencies and damping properties of metal foams. Due to the strongly developed inhomogenities of the microstructure of metal foams the material parameters and properties fluctuate.

The influence of the inhomogenities at the micro level to the macroscopic behavior is being researched. Two aspects are of main interest: The size effect and the standard deviation of the material parameters. The aim is to develop a simulation model that depicts the influence of the microstructural inhomogenities on the macroscopic behavior.
