采用基于Huang等提出的塑性应变梯度传统理论发展的有限元方法，模拟了颗粒增强金属基复合材料的界面开裂与颗粒尺度效应．分别针对考虑颗粒与基体间界面开裂和不开裂两种情况进行分析，并将考虑界面开裂的模拟结果与实验结果进行比较，证明了模型的有效性，同时也获得应变梯度理论中所包含的材料特征尺度参量的取值． |

In the present study, interface cracking effect and particulate size effect of the particle-reinforced metal-matrix composite are modeled adopting the finite element method which is based on the conventional theory of mechanism-based strain gradient plasticity （CMSG） theory presented by Huang et al. Two interface cases of the particle and substrate are considered, respectively, which are corresponding to cracking interface and intact interface. The comparison of modeling results considering the interface cracking with experimental measurements is performed for testifying the present model. Through comparison, the length scale parameters included in the strain gradient plasticity theory are determined. |
