(a.) If the displacements in a two dimensional, plane stress model have the variations shown below (at x=1, y=1) find the strains, and find the stresses if the material is isotropic and elastic.
Let a = 0.5, b = 0.4, c = 0.3, d = 0.2, e = 0.1, E = 1, and nu = .3
u(x,y) = a x^2 + b y^2 + c x + d y + e
v(x,y) = a y^3 + b x^2 + c y + d x
The data is designed to ease the computation, so the results don't corespond to a realistic situation.
(b.) Go through ANSYS Tutorial Lessons 1 and 2. Submit a print of the following items for each lesson. (or equivalent if you're using NASTRAN or other FEM code)
