Nizhnii Novgorod, USSR aut Criteria of the contact strength, ductility, and fracture of materials in shear with buckling [Elektronische Daten] [A. Vesnitskii] A model is presented of the origination and suppression of the fracture of a contact surface during shear of its layers. The process is examined as a function of the configuration of projections on the rigid body, the thickness of the layers undergoing deformation, and the distribution of the contact stresses. Two mechanisms of fracture suppression on the contact surface are found: an unstable mechanism dependent on the thickness of the layer undergoing shear and the properties, roughness, and condition of the surface of the material being deformed; a stable mechanism independent of these factors. Both mechanisms are found to be of practical value in the solution of problems which involve increasing the strength of contact layers and resistance welds in various structures and optimizing regimes of plastic deformation and resistance welding. Criteria of contact strength are also presented for ductile and low-ductility materials.
