摘　　要：主要研究了网孔材料的力学性能。在均匀化理论的基础上,通过有限元软件ABAQUS计算了蜂窝孔材料和密排圆孔材料的等效弹性参数随实体率的变化规律,并提出两种网孔材料力学性能的比较分析。研究表明:当实体率相同时,密排圆形网孔的等效弹性模量和等效切变模量均大于蜂窝网孔。研究成果对工程实践中推广使用密排圆孔材料具有很大的价值。In this paper, the mechanical properties of mesh materials are studied. Based on the theory of Homoge- nization, the variation rule of honeycomb mesh material and packed round mesh material is calculated with the help of ABAQUS, and the comparative analysis of these two kinds of mesh material is put forward. The results show that when the entity rate is the same, the equivalent elastic and shear modulus of packed round mesh material are big- ger than honeycomb mesh material. This result is raluable for the promotion of packed round mesh material in the engineering practice.
