Abstract
This work applies Gurson model to the simulation of damage in metallic foams. In the first part, two approaches for Gurson model application, i.e., the hypoelastic and the hyperelastic formulations are compared. Then, a study on the minimum number of cells to be employed in an experimental test to adequately simulate the behavior of the cellular material in tension is presented. Finally, considering that compression is the dominant loading in impact situations, a simulation including damage effects of a compression test on a cellular metal sample is shown and compared with experimental results.
