Abstract

Nonlinear fracture mechanics of metal foams is discussed. The equivalent continuum constitutive model is introduced first. Then we studied analytic solutions on plastic analysis based on generalized cohesive force model, approximate analytic solution of elasto-plastic analysis for central crack, single edge crack specimens in tension and bending, respectively. The finite element analysis is also conducted. In addition, the crack slowly growth and fast propagation are studied as well.Atthe end we proposed a fracture criterion on metal foam.
