Week 1 Stress Concentration on a Plate with hole

The deformation and maximum stress developed on a structural steel model for 2 cases:

Case:1 case:2

Deformation (mm) 0.00027 0.00029

Maximum stress (MPA) 0.604 0.581

From the analysis, we can select the case:2 model which is having less stress than the case:1

From a manufacturing point, we can select model which is having one hole (if we need less manufacturing cost).
