Bounds of Stiffness of Composite Materials with Imperfect Ellipsoidal Interface under Finite Deformation

应用文献［１３］中有限变形下非完美界面弹性复合材料有效模量的近似公式和微分几何方法，计算了含一般旋转椭球体夹杂弹性复合材料有效体积模量和有效剪切模量的上下限界。所得结果为研究大变形下实际弹性复合材料的刚度估值提供了定量判据。

Upper and lower bounds of effective bulk and shear moduli for elastic composite materials with general ellipsoid of revolution inclusion have been calculated by using the approximate formulae,which related to the effective moduli of composite materials with imperfect interface under finite deformation,in reference .Thus the results obtained above provide the quantitative criteria for estimate of stiffness in researches practical composite under that.
