| Abstract: | In this paper the compressible plasticity of metal foams are discussed so as to deduce the finite element formula in 3-D space state, plane stress plane, plane strain and axial-symmetry state to demonstrate the contribution of the continuum constitutive model, which is helpful to improve understanding of the plastic compressible mechanical response of metal foams. |
| Keywords: | metallic cellular materials(metal foams) compressible plasticity continuous constitutive model finite element formula |
