Phenomenological Material Model of Foam Solids

Abstract

Abstract In this contribution a new phenomenological model for pressure loaded foam materials is proposed. The presented relationship between compressive stresses and compressive strains is derived by using simple rheological models. The proposed model contains several parameters. The procedure of their identification and the influence of parameters on a curve shape are also explained. The accuracy of our model is tested and compared with other phenomenological models. These tests have been applied on aluminium and polyurethane foams.
