文摘

●A stretch factor R is used to characterize the transversely isotropic degree of cellular materials.●A pressure-dependent constitutive model based on four stress-strain paths is proposed for transversely isotropic foams.●The pressure-dependent model can accurately predict the initial/subsequent yield responses of transversely isotropic foams.●Effects of the macroscopic and microscopic material parameters on the yield behavior are investigated.
