1)(One-Dimensional Equivalent Strain) A bar is under axial stress σ and axial strain ε. Calculate the equivalent stress and effective strain in terms of σ, ε, and Poisson’s ratio ν.
2)(Pure Shear Deformation) Consider a pure shear deformation of a plane strain square block, as shown in Fig. 4.12 where a constant shear stress τ is applied. The yield stress of the material is σY. Calculate the shear stress τ when the material yields using the yield function formula in Eq. (4.70).
