The plane stress problem i.e a plate under uniform tension at its edges is solved. Plate is dicretized using isoparametric Q4 elements. Pre-processing is done using a standard FEM software. 2nd order Gaussian integration is used to get stiffness matrix. Results obtained are compared with standard FEM software, both the results are in good agreement.
