A finite element model of the local mechanical response of a filled polymer composite to uniaxial compression is presented. The interfacial layer between filler particles and polymer matrix is explicitly modeled as a third phase of the composite. Unit cells containing one or several anisometric filler particles surrounded by interface shells are considered. The dependence of the mechanical response of the cells to external deformation on the interface thickness and stiffness is studied. The use of the particle-matrix interface as a damping tool in mesoscopic polymer-composite problems with large deformations is discussed. The influence of the interface on the anisotropy of the composite response is considered.
本文提出了一种填充聚合物复合材料在单轴压缩下局部力学响应的有限元模型。填料颗粒与聚合物基体之间的界面层被明确建模为复合材料的第三相。考虑了包含一个或几个被界面壳包围的各向异性填料颗粒的单胞。研究了单胞的力学响应对外界变形的依赖性与界面厚度和刚度之间的关系。讨论了在大变形细观聚合物复合材料问题中，将颗粒 - 基体界面用作阻尼工具的情况。考虑了界面对复合材料响应各向异性的影响。
