Simulation of plates with hole

Aim: Perform a static analysis on two models of the plate with holes

Modeling:

We have the dimensions of the plates with holes

• for case 1 :Length=300mm,Height=120mm,Thickness=30mm,Circular Hole at the center,Diameter=60mm

• for case 2: Length=300mm, Height=120mm, Thickness=30mm, Circular Hole at the center, Diameter=60mm, and Two holes of 30 mm diameter which are placed 90mm away from the central hole on both sides.

Simulation:

• Select the static analysis study
• apply the default material which is alloy steel
• Fix one of the small faces and apply the tensile load of 1000N on another one

Fixed face

Tensile loading of 1000N:

• Mesh the part to the finest to get more accurate results

• Run the simulation

Results:

• case 1

• Case 2

Conclusion:

From the study, we can say that the stress concentration near the holes increases since cross-sectional area decreases causing the decreases in the resistance and therefore overall displacement also increases
