| Abstract: | Damage models of material failure by microvoid nucleation and growth to coalescence are described.Approximate constitutive relations are used,to model both the nucleation and growth of the microvoids.The Crack growth has been numerically analyzed,based on damage medel of finite element method and compared with the experiments of compact tension specimen successfully. |
