Plane Stress
The state of plane stress exists when there is only one zero component of principal stress where \(\sigma_3=0\), \(\sigma_1\ne0,\ \sigma_2\ne0\). The geometry used in this case is a 10*10*2 plane with no body force subjected. Dirichlet boundary conditions are spcified as fixed displacements towards the center of the plane to represant plane stress. The magnitude of the displacement of front, back, left and right boundary is 5, move toward the center of the domain. Result shows that strain decreases towards the center of the plane. And the conors are where the yield will first occor assuming isotropic material, which, again, might be artifically caused by boundary condition. The rest of the domain shows basically equal Magnitude of von Mises stress.
