The calculations were performed with the use of the finite element method with utilization of elements of various approximating polynomials orders. Each type of element underwent tests for different characteristic size of element. Precision of numerical calculations for stress concentration factor Kt was compared to errors of analytical calculations performed with employment of various approximate methods. The results gained in the work allow to indicate optimal mesh size and type of finite element providing precise Kt value with minimal DOF number.
