摘要：

       聚合物基质复合材料由于其优异的机械性能自20 世纪60 年代就越来越广泛地应用于航空业和汽车业。然而，由于复合材料的断裂模式非常多样和复杂，对于复合材料损伤以及断裂的预测仍然是一个很大的挑战。该文总结了复合材料断裂的主要模型和方法。方法可分为3 类：断裂准则法、连续介质损伤力学法和塑性法。断裂准则法主要考虑复合材料的起始或者最终的断裂极限；连续介质损伤力学法考虑了材料弹性模量的衰减；塑性法则是把材料的非线性性能当做塑性来考虑。复合材料分层的模型法，作为一种很特殊的失效模式，也包括在这篇综述中，这种失效跟纤维的方向和层板的组合方式很有关系。该文对这些模型的相对优势和劣势也进行了总结。

Abstract:

Fiber reinforced polymer matrix composites have been found increasing applications in automotive and aerospace industries since 1960s due to their super mechanical properties. However, accurate prediction of composites damage and fracture are still very challenging because failure modes of composites are very
complex. This review paper summarizes the major modelling methods for composites damage. These methods are classified into three categories, which are the failure criterion method, the continuum damage mechanics method, and plasticity method. The failure criterion method considers the initial or the final failure loci of composites, while the continuum damage mechanics method takes the degradation of material elastic modulus into account. The plasticity method considers the material non-linear behaviors as plasticity. The delamination modelling methods are also reviewed since it is a special failure mode for composites, which greatly depends on the fiber directions and laminate layup. A summary of the advantages and drawbacks of these modelling methods are also provided.

Key words: composite materials, composites fracture modelling, failure criterion method, continuum damage mechanics method, plasticity method, delamination modelling
