Plastic analysis of central crack specimen of cellular/foam materials

An approximate analytic solution of elasto-plastic analysis for central crack specimen with finite width W in cellular/foam material is given based on generalized cohesive force model, and crack tip opening displacement is determined, which may be useful for plastic fracture experimental study and engineering applications of the advanced material.

► A comprehensive description on the deformation and fracture of metal foams.
► Give the analytic solution in closed form of finite size specimens of foam solid.
► Reveal quantitatively the nonlinear behavior of fracture of the advanced material.
