Popis:	This paper compares the mode I boundary correction factor solutions for two symmetric elliptical cracks emanating from a straight-shank hole. A variety of methods were used to generate the solutions. A global–intermediate–local hierarchical approach was developed using the finite element method (FEM). Comparisons were made with the following methods: the FEM with the equivalent domain integral, semi-empirical stress-intensity factor (SIF) equations, the finite element alternating method, the boundary element method (BEM) with the crack opening displacement approach, the BEM using special crack-tip elements, and the three-dimensional weight function method. The SIF solutions were within a band of ±3% about the average solution.
