  1. 1. Dominic Waldorf ME 471 Dr. Pourboghrat March 26th , 2015 FEA Design PART 1: Mesh Size: 5 mm Mesh Size: 10 mm
  2. 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.
  3. 3. PART 2: Mesh Size: 5 mm Stress Element:
  4. 4. Displacement:
  5. 5. Mesh Size: 10 mm Stress Element:
  6. 6. Displacement:
  7. 7. Mesh Size: 20 mm Stress Element:
  8. 8. Displacement: 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.
