Week 1 Stress Concentration on a Plate with hole

Please see below comparison of two plates with various parameters

Also we have a reference that Structural steel has a yield strength of 240MPa

Compared to Yeild strength of steel, both the parts will be intact and will not fail.

Sl. No	Description	Rectangular Plate with 1 hole	Rectangular Plate with 3 holes
1	Max. Von Mises Stresses (MPa)	0.605	0.582
2	Max. Displacement (mm)	0.00027	0.0003
3	Mass (g)	7812	7479

So from analysis side, the plate with 1 hole is better as it have higher internal stresses as compared to plate with two holes. Deformation in both is very small and can be neglected.

From manudacturing side, the plate with 2 holes is better as compared with plate with 1 hole as it is lesser in weight. This also means less material and hence less cost.
