Finite Element Analysis on a Plate with Hole using Solidworks

Analysis on a Plate with Hole

Objective :

• To perform Static Analysis on two different plates with Holes.
• To evaluate for Stress, Strain and Displacement.

The 2 Geometric Models are as follows,

**All dimensions are in mm

Pre Conditions :

• Material is Alloy Steel
• Type of Analysis :- Static Structural
• 1 of the shortest side is fixed.
• Tensile load of 1000N acts on other shorter end.
• Since Models are simple, Finer mesh is applied allover.

Material Properties :- Alloy Steel

Conclusion

• The Stress developed in the case 2 (Plate with 3 Holes) is less compared with case 1, because of providing Stress releiving holes on either side.
• Providing smaller holes on either side of Bigger hole has resulted in reducing Stress Concentration.
• Both the Plates are subjected to similar Boundary Conditions and loading and Plate 2 is considerably Good since it has less material than Plate 1 (Weight Reduction) and lesser Stress Concentration.
• Both the Plates are well within the yield limit and hence are Safe interms of Design.
