This lecture covers the evaluation of material behavior in shear, focusing on shear forces and stress. It discusses the primary and secondary shear stresses, equilibrium of moments, and the existence of shear laws in different directions. The lecture also delves into the state of shearing and tension/compression, as well as the concept of plane shear in x, y directions. Additionally, it explores the relationship between shear stress and shear rate, the concept of constrained slip, and the shear strength of materials. The importance of plasticity criteria in studying material processes is highlighted, with a focus on permanent deformation levels and widely used plasticity criteria.
