【摘要】 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文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。更多还原

【Abstract】 This paper introduces a general form of the constitutive equation of non-linear hyper -elastic orthogonal anisotropic material based on the density of complementary strain energy with the help of the invariant theory.A new method measuring the coefficients of the non-linear constitutive relation of the material is also presented in this paper according to the theory of stress wave propagation.With the use of this method the coefficients of the composite materials rein-foreed with fibreglass are determined.更多还原
