Szukana fraza: [Abstract = "The paper presents a comprehensive analysis of the stress field near a crack tip for a compact specimen dominated by the plane strain state using the finite element method. The analysis also includes the calculation of some parameters of in\-plane constraints, both for small and large strain assumptions. It discusses the influence of the material characteristic, relative crack length and external load for the stress field, and the in\-plane constraint parameter. The approximation formulas for some in\-plane constraint parameters are presented."]
