WebFlow Theory of Plasticity – Handout 4 Henry Tan, Spring 2009 2 Exercise 1 Proof that εpp=ε in a uniaxial tensile test in which the specimen is stretched parallel to e1 direction (εp is the plastic strain in e1 direction). Solution: During plastic deformation, p 0 ε WebAn object or material is elastic if it comes back to its original shape and size when the stress vanishes. In elastic deformations with stress values lower than the proportionality limit, … WebLearning Objectives. By the end of this section, you will be able to: Explain the limit where a deformation of material is elastic. Describe the range where materials show plastic behavior. Analyze elasticity and plasticity on a stress-strain diagram. We referred to the proportionality constant between stress and strain as the elastic modulus. orbn building
