This paper deals with both size and shape of plastic zone in the vicinity of the crack edges. Determination of plastic zone is proposed using the three-dimensional finite element analysis. Both, linear elastic and elastic-plastic material models are considered in this paper. Subsequently, results of these approaches are compared and their applicability is evaluated. Geometry considered is a beam with L-shaped cross section containing a crack, as it is described below. Mentioned beam is subjected to mixed mode loading condition, that is represented by variable forces in the direction of global coordinate system. Evolution of plastic zones is observed and evaluated around the crack edges of the profile.
