) that characterize the isotropic elastic properties of a material. 2. What is the Theory of Plasticity?
Proposes that yielding begins when the distortion strain energy per unit volume reaches a critical value. It is represented mathematically by an elliptical yield surface in principal stress space.
In the linear elastic region, stress is directly proportional to strain. This is mathematically expressed as: σ=E⋅ϵsigma equals cap E center dot epsilon represents Young's Modulus (the modulus of elasticity).

Linear Elastic Behavior (Hooke's Law): Stress (σ) = Modulus of Elasticity (E) × Strain (ε) Key Concepts in Elasticity
Materials often become stronger as they deform plastically (work hardening). Isotropic and kinematic hardening models simulate how the yield surface expands or shifts during loading. How to Access Verified Engineering Textbooks Safely
