This paper presents an approach to describe a mathematical model of elastic - plastic stiff foam. Stress-strain curves obtained from real test were used to build a FEM model of tested foam: the "crushable foam" material has been used to define a mechanical properties. Main part of the article is devoted to numerical simulations in ABAQUS: static (uniaxial compression test) and dynamic (simulation of impact). The article presents also a possibility of usage of the tested foam in a bicycle with an energy-consuming body.
