Results and Post Processing :

We apply loading for each case and the results are presented below :

We plot the graphs and find the stress and the deflection for each of the cases and the graphs

are plotting below.

1. CASE 1 : Pure Bending

We can observe from the above graphs that the maximum deflection is at the right most edge

and the maximum stress occurs at the bottom most edge.

The stress and deflection are more pronounced for LST and Q8 than CST and Q4 element types.

2. Case 2 : Pure shear in y direction on the free end.

As we can see from the above graphs that the maximum deflection occurs at the right most

edge and the maximum stress occurs at the bottom left point.

The stresses and deflection is more pronounced in the Q8 and LST than the CST and Q4 element

types.

3. Case 3 : Uniformly distributed load on the top of the cantilever beam

As we can see from the above graphs that the maximum deflection occurs at the right most

edge and the maximum stress occurs at the bottom left point.

The stress and the deflection are more pronounced in the Q8 and LST than the CST and the Q4

element types.
