本文提出了一种分析正交各向异性复合材料（如玻璃纤维增强酚醛塑料）动态断裂性能的广义Shmuely差分算法。推导了差分递推公式和边界条件差分外推公式，并编制了相应的程序。用GSDA方法分别计算了各向同性和各向异性中心裂纹板的动应力强度因子，并与已有的结果进行了比较。GSDA被证明是有效和可靠的。
The generalized Shmuely Difference Algorithm (GSDA) is presented here to analyze the dynamic fracture performance of orthogonal-anisotropic composite materials, such as glass fibre reinforced phenolplast. The difference recurrence formulae and boundary condition difference extrapolation formulae are derived and programmed. The dynamic stress intensity factors (DSIF) of the isotropic and anisotropic centrally cracked plates are computed respectively using GSDA and compared with that published previously. GSDA is proved effective and reliable.
