Week 1 Stress Concentration on a Plate with hole

Case 1: Maximum stress: 1.2121 MPa and minimum 0.015841 MPa

Case 2: Maximum stress: 0.46412 MPa and Minimum 0.0078452 MPa

Case 1: Maximum deformation: 0.00054984 and minimum deformation : 0 mm

Case 2 : Maximum deformation : 0.00024246 MPa and Minimum deformation : 0 mm

For analysis, point case 2 be selected due to less stress and deformation

and from a manufacturing point of view the case 1 be lesser cost and be selected.
