Originální abstrakt

It has been shown that the so-called multi-parameter approach for approximation of the crack-tip stress and displacement fields can help to express the stress distribution better than if the only one or two parameters are used (as it is usual). Further investigations in this area are introduced in this paper. The Williams expansion (WE) is used for the stress state description and subsequently also as an input for the fracture criteria enabling prediction of the crack path and estimation of the plastic zone size. It means that the criteria are used in a kind of their generalized form. This study represents a short summary of the authors' complex investigations devoted to influence of the higher-order terms of the WE on various fracture characteristics/phenomena (near-crack-tip stress field approximation, crack propagation angle, plastic zone extent, etc.).
