In geology, a shear zone is a thin zone within the Earth's crust or upper mantle that has been strongly deformed, due to the walls of rock on either side of the zone slipping past each other. In the upper crust, where rock is brittle, the shear zone takes the form of a fracture called a fault. In the lower crust and mantle, the extreme conditions of pressure and temperature make the rock ductile. That is… Web1 Mar 1971 · The width of the secondary deformation zone and the mean coefficient of friction were found to be direct functions of the parameters involved in the cutting … WebSecondary Shear Zone (SSZ): It lies between the metal chip and cutting tool.

Web1 Jan 2024 · Definition. In metal cutting processes almost the entire mechanical energy is converted into heat. Sources of heat are the primary shear zone and secondary shear zones at the rake and flank face. Heat partitioning describes the fractions of heat dissipated by the tool, the workpiece, the chips, and the cutting fluid. WebThe shear angle φ is the angle at which the shearing phenomenon occurs, as the shear stress reaches the material shear strength. In analytical cutting force modeling, the shear angle φ is one of the most important factors which has great influence on chip shape and cutting forces, whether using the shear plane method or using the shear zone method.
