Elastoplastic Analysis The problems for Section 2.12 are to be solved assuming that the material is elastoplastic with yield stress s Y , yield strain e Y , and modulus of elasticity E in the linearly elastic region (see Fig. 2-70). Problem 2.12-1 Two identical bars AB and BC support a vertical load P (see figure). The bars are made of steel having a stress-strain curve that may be idealized as elastoplastic with yield stress s Y . Each bar has cross-sectional area A . Determine the yield load P Y and the plastic load P P . Solution 2.12-1 Two bars supporting a load P SECTION 2.12 Elastoplastic Analysis 171 P B AC uu P B P B s Y A s Y A u Structure is statically determinate. The yield load
