Objective
Developed a Matlab code for finite element solution of cantilever beam subjected to shear force and varying load to perform a convergence study for calculating maximum principle stress and maximum displacement.

Project report
Reslts
For the condition of loading and displacements, the results are as predicted. Since the load is a shear load, the stresses are more on the tip rather than in the fixed end. The convergence study among the Q4 meshes showed that error reduced by a factor of 100 when mesh size was halved. For t3 the convergence was steeper when mesh size was halved error only reduced by a factor of 10. The quad element is more accurate than tri element. But cost of computation for quad is higher.
