(Uniform Tension of a Cube) Consider a unit cube as shown in Fig. 4.26.An eight-node solid element (C3D8) is used to model the cube. The positive X₁ face (Face 4) is extended with a strain ε=0.004. The following boundary conditions are given: u₁=0 at Face 6, u₂=0 at Face 3, and u₃=0 at Face 1. Using Abaqus, calculate the relation between Cauchy stress and strain. Use elastoplastic with isotropic hardening material. The elastic properties are E=200 GPa and ν=0.3. The initial yields stress is σ_Y=200 MPa and is linearly hardened until 220 MPa at logarithmic strain ε_ln=0.002. After that, there is no hardening (see Fig. 4.25). Compare the stress–strain curve from the material definition and the response from Abaqus.
