4. (23 pts) A plate is loaded so that a state of plane strain (Ezz- &zx=&zy =0) exists. (a) Determine the displacements for the plate for the deformations shown, i.e. finding u-Cixy and v=C2xy. (b) Determine the strain components at point B. (c) Determine the stress components at point B, assuming the materials is elastic isotropic (Young's modulus E-1 GPa and Poisson's ratio v=0.2). (d) Let the X extend from point O through point B. Determine exx at point B. A 0 A* 3.0 m 0* 1.5 m- |--3 mm 11 B C B 6 mm K Straight lines C* x 4.
