摘　　要：为了研究界面层厚度对HEA_(p)/Ti复合材料力学性能的影响以及拉伸过程中复合材料的破环行为,使用ABAQUS有限元分析软件对单颗粒和多颗粒模型进行不同界面层厚度建模。模拟结果表明:随着界面层厚度的增加,界面层上的应力也变大。复合材料拉伸破坏主要是基体开裂和界面脱粘。在拉伸过程中,复合材料的裂纹首先在界面层处萌生,随着载荷的增加,裂纹沿颗粒在基体中扩展。In order to study the influence of the interface layer thickness on the mechanical properties of HEA_(p)/Ti composites and the ring-breaking behavior of the composites during the tensile process,ABAQUS finite element analysis software was used to model single-particle and multi-particle models with different interface layer thicknesses.The simulation results show that as the thickness of the interfacial layer increases,the stress on the interfacial layer becomes larger.The tensile damage of composites is mainly matrix cracking and interface debonding.During the tensile process,the cracks of the composites first sprout at the interfacial layer,and with the increase of load,the cracks expand along the particles in the matrix.
