正交各向异性材料动态力学性能的理论与实验研究

从余能密度出发，以不变量理论为工具，导出了非线性超弹性正交各向异性材料本构关系的一般形式，提出了一个以波传播理论为基础的测定材料非线性本构关系参数的新方法，并用这种波动实验方法具体测定了玻璃纤维增强复合材料的非线性动态本构关系参数。

THEORETICAL AND EXPERIMENTAL STUDY OF THE DYNAMIC BEHAVIOR OF ORTHOGONAL ANISOTROPIC COMPOSITES

This paper introduces a general form of the constitutive equation of non-linear hy-per-elastic orthogonal anisotropic material based on the density of complementary strain energywith the help of the invariant theory. A new method measuring the coefficients of the non-linearconstitutive relation of the material is also presented in this paper according to the theory of stresswave propagation. With the use of this method the coefficients of the composite materials rein-foreed with fibreglass are determined.
