Ah&act-Three iterative methods for the numerical determination of stress intensity factors at crack tips (by using the method of singular integral equations with Cauchy-type kernels) are proposed. These methods are based on the Neumann iterative method for the solution of Fredholm integral equations

A modification of the collocation method for the numerical solution of Cauchy-type singular integral equations appearing in plane elasticity and, especially, crack problems is proposed. This modification, based on a variable transformation, applies to the case when the unknown function of the singul
The calculation of stress intensity factor for a sharp V-notch is done from the limiting value of stress concentration factors as the root radius of the same V-notch rounded at the tip approaches zero. The stress analysis is carried out using the complex variable formulation of Muskhelishvili and th
It is shown in this paper that two-dimensional interface problems with large jumps in the coefficients can be solved effectively by the piecewise linear finite element method on quasi-uniform grids. This is achieved by combining the full multigrid methodology, the singular function representation of
