摘要
描述了基于材料微观空穴成核、长大和聚合的损伤力学模型，用增量本构关系模拟了空穴的成核和长大。用有限元损伤模型计算了裂纹的扩展。
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.
