Originální abstrakt

Various cracked configurations have been chosen in order to investigate the importance of the higher-order terms of the Williams' power expansion for the crack-tip stress field distribution. The higher-order terms are calculated by means of the over-deterministic method from displacements of nodes around the crack tip. The effect of the constraint level is investigated. Although the third and higher terms of the Williams' series are neglected very often, their influence on the opening stress values is investigated. The results are compared to numerical results obtained by means of the finite element method in the commercial FE code ANSYS. Several conclusions are stated and discussed.
