中文摘要:
      本文利用Fourier变换方法和Weber-Schafheitlin间断积分,求得裂纹尖端附近位移场精确解的封闭形式,从而改进了断裂力学中Williams复特征展开式级数解的主项位移场公式.
英文摘要:
      Given in this paper are formulas of the closed form for the exact solution to the displacements near the tops of the cracks by means of Fourier Transform and Weber-Schafheitlin integral. Thus, they will improve the results of the displacement in fracture mechanics by the first term of Williams expansion.
