Consider a plane stress problem, as shown, assuming thickness h 1, the material is homogeneous, Young s modulus E 1, Poisson s ratio v 0, the correlation force and displacement boundary conditions shown in the figure , The left side of the problem is a fixed constraint. Try using two triangular cells to analyze this problem. The displacements u, v and stress σ_x, σ_y and σ_xy of each node are calculated.
