WebThe secondary shear zone is characterized from higher value of strain (10-20), and strain rate. Several flow-zone models have been used to explain tribo-layer phenomena (Trent [3], Oxley [4] and Qi and Mills [5]). Guo [6] proposed a mechanical behavior characterization of the SSZ. In this paper an analytical model of the primary shear ... WebDeformation takes place along a narrow shear zone called the primary shear zone. Some continuous chips may develop a secondary shear zone at the tool/chip interface. This zone becomes thicker as friction increases. Continuous chips also may occur with a wide primary shear zone that displays curved boundaries.
