PART 1:
Mesh Size: 5 mm
Mesh Size: 10 mm

2. Mesh Size: 25 mm
Element Stress (AISI 1005):
Mesh Size 5 mm:
Hole: 8.059 N/mm^2 (MPA) Semi-circle: 6.050 N/mm^2 (MPA)
Mesh Size 10 mm:
Hole: 7.328 N/mm^2 (MPA) Semi-circle: 5.999 N/mm^2 (MPA)
Mesh Size 20 mm:
Hole: 6.588 N/mm^2 (MPA) Semi-circle: 5.023 N/mm^2 (MPA)
Relationship:
The mesh size and the maximum value of stress are inversely proportional. As mesh size
increases, the maximum value of stress decreases. 

Maximum Stresses and Deflection for Aluminum 6061 bar:
Mesh Size 5 mm:
Max Stress: 778.81 N/mm^2 Deflection: 62.87 mm
Mesh Size 10 mm:
Max Stress: 617.92 N/mm^2 (MPA) Deflection: 58.07 mm
Mesh Size 20 mm:
Max Stress: 446.72 N/mm^2 (MPA) Deflection: 48.85 mm
Relationship:
The mesh size and the maximum value of stress are inversely proportional. As mesh size
increases, the maximum value of stress and deflection decreases.
