Cellular materials are strongly related to pressure level inside the material. It is therefore important to use experimentswhich can highlight (i) the pressure-volume behavior, (ii) the shear-shape behavior for different pressure level. Authors proposeto use hydrostatic compressive, shear and combined pressure-shear tests to determine cellular materials behavior. Finite ElementModeling must take into account these behavior specificities. Authors chose to use a behavior law with a Hyperelastic, a Viscousand a Hysteretic contributions. Specific developments has been performed on the Hyperelastic one by separating the sphericaland the deviatoric part to take into account volume change and shape change characteristics of cellular materials.Read less <
