The object of this paper was fracture mechanic modelling of solids using finite element (FEM). The main tool that has been utilized was the software Mcrack which is a group of macros intended for use jointly with ANSYS finite element program. One major advantage of the Mcrack software is that it supports solid modelling with a crack located at an arbitrary location. This implies that it is possible to calculate also torsion and mixed mode cases within a most reasonable work effort. However, Mcrack was developed to cover complex weld geometries. Utilizing Mcrack for general solid modelling requires an analysis of the possibility of development for arbitrary crack paths. As test object a cast sleeve made of nodular iron has been used. Previous to this investigation the component was submitted to a test program and a subsequent evaluation according to S/N criteria's at ABB, Sweden. This paper is thus a continuation of the ABB work, and at the same time an extension of the field of application for the Mcrack software. For validation purposes the software AF-Grow as well as elementary cases has been used in parallel. The investigation is a part of the nordic project "Cast Design 2005".
