%X This paper deals with the determination of stress intensity factors in a WC-6Co sample through the Finite Elements Method (FEM). A compact specimen configuration, used in fracture testings, was numerically modelled with the FEM commercial code MARCTM. First, in studying of this specimen was considered a bidimensional strain plane analysis. Several meshes were used in the tested models and then results were compared with the experimental data, that can be found on technical literature. Finally, a tridimensional compact specimen was also modelled and studied. With these results, we were able to understand better the triaxial stress behaviour in the central portion of the specimen. It¡¯s hopeful this methodology will be applied in nonconventional fracture mechanics testings, such as a Vickers indentation technique.
