Abstract
Cellular materials, like metal foam, have a good energy absorption capacity. To design technical applications there is a need to know material properties. Here is a problem, still today not all the parameters are known. To make matters worse nearly all material properties of metal foams are a function of density. Furthermore, for energy absorption there is the question if there is also a strain-rate dependency or not. Here are different points of view found in literature. Some authors report about strain-rate dependent stress behaviour, others deny it [3, 4]. So a new investigation was set up, with a standardised sample size. In that investigation a strain-rate dependency of stress levels and also energy absorption was found.
