On comparing both the stress and deformation values of two structures, it is clear that theere is huge change in deformation value where as change in stress values is not too huge.
- I would select design 2 as we can see that the deformation is very little even after applying same load on both the designs. But the only care that is to be taken is using the higher number of elements on the stress concentrated areas for extracting the accuracy in the result.
- I would select design 2. The reason behind this is from analysis we came to conclusion that design 2 suits better for our application. The material quantity that is used is less than design 1. This helps in saving the material to certain extent with better outputs.

DESIGNING THE PLATES:
In case1 we used structural steel plate with a hole of dia 60mm and in case 2 we used a plate with 3 holes, one with dia 60 and rest of the 2 circles with dia 30.
Applied Load:
In both the cases we applied same load of 500N but the boundary conditions varies. In case1 we used a fixed roller support with movement only in 1 direction. In case2 we used a fixed support fixed in all directions.
Stress and Deformation analysis:
For a better quality of meshing and accuracy, we used a element size of 5 for case1 and for case 2 element size of 10 is used. After meshing and solving both the cases we got the results as shown below:

Inference
As discussed above we have got the same stress values but difference in deformation values. As we know that case 2 has less deformation when compared to that of case 1 with less volume of materil used we can say that design 2 can be used for various applications.
