摘要
采用线弹簧型弱界面模型来模拟柔性涂层 ,研究柔性涂层对复合材料宏观弹性模量的影响 .首先利用Mori Tanaka方法和弱界面球形夹杂问题的弹性解 ,获得单夹杂内部的平均应力和平均应变 ,进而求得具有柔性涂层的复合材料的宏观弹性模量 ,并研究界面柔度对复合材料弹性模量的影响 .
The effect of soft coatings on the elastic moduli of composite materials is studied, in which the coating is modeled by a linear spring type imperfect interface. The Mori Tanaka model and the elastic solution of a single inhomogeneity with an imperfect interface are employed to calculate the average stress and strain in the inhomogeneity. The effective elastic moduli of composite materials with soft coatings are then obtained. Finally, the effect of interfacial compliances on the effective properties of composite materials is studied.
