摘要
本文采用Fourier变换,推导了纵向剪切问题间断位移、周期间断位移以及半平面间断位移的理论解,并由此建立了一组求解含裂纹与孔洞问题的线性方程。几个较为复杂的数值算例证明了本方法具有较高的精度和好的收敛性。
In this paper, by the use of the Fourier transformation, the author derived the theoretical solution of the stress intensity fators for the longitudinal shear problem with piece-wise displacements, cyclic piece-wise displacements and piecewise displacements on a half plane body, whence to establish a set of linear equations to solve the cracked plane problems and plane problems with holes. Many of the numerical examples indicate that the suggested method of this paper possesses good accuracy and rapid convergency.
