Pyramidal Model of Intergranular Crack Front
Original language description
The simple pyramidal-like model is introduced as suitable approximation of the real geometry of intergranular crack fronts in metallic materials. The extrinsic component of the measured fracture toughness KIc can be estimated by means of this model. Standardly measured materials data as the yield stress, the mean grain size and the linear surface roughness are needed for application of this simple approach. Values of the global effective stress intensity factors received in the framework of the pyrramidal model agree well with those obtained for complicated real-like intergranular geometries constructed on the bases of 3D Voronoi tessellation.
