In a preceding paper (Pampolini and Del Piero in J Mech Mater Struct 3:969–981, 2008 ), the response of blocks made of a polymeric open-cell foam subject to uniaxial compression was analyzed. The hysteretic behavior exhibited in cyclic tests was interpreted within the context of nonlinear elasticity...
