FEA Design PART 1:

Mesh Size: 5 mm

Mesh Size: 10 mm

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.
