Analysis on a Plate with a Hole

AIM:

To compare the performance of 2 separate plates with different hole geometries  by performing a static structural analysis using Solidworks Simulation and determine and plot the Von Mises Stresses, Strain and Displacement and compare findings.

• SOFTWARE USED:

Solidworks 2017

• Pre-requisites:

The 2 plates with different hole profiles are modeled in Solidworks using the Solid modeling tools.

• Boundary conditions:

Part type = Plate with hole/s

Material = Alloy Steel (See figure 2 for Material properties) 

Tensile load = 1000 N (pulling on one of the shorter sides of the plate – 120 mm X 30 mm surface)

Experiment 1: Rectangular plate with 1X 60 mm hole

• Setup: A new Static study was created in Solidworks Simulation.
• Boundary conditions: Alloy steel was applied as the material; one of the 120 mm X 30 mm face is fixed and a tensile load is applied on the opposite 120 mm X 30 mm face so that it stretches the plate.
• Mesh: A mesh size of 3 mm is chosen and applied.
• Results: The mesh is applied and the simulation is run. The plots are generated and compared. The results are tabulated in the results section of the report.

 Experiment 2: Rectangular plate with 1X 60 mm and 2X 30 mm hole

• Setup: A new Static study was created in Solidworks Simulation.
• Boundary conditions: Alloy steel was applied as the material; one of the 120 mm X 30 mm face is fixed and a tensile load is applied on the opposite 120 mm X 30 mm face so that it stretches the plate.
• Mesh: A mesh size of 3 mm is chosen and applied.
• Results: The mesh is applied and the simulation is run. The plots are generated and compared. The results are tabulated in the results section of the report.

Inference:

• The 2 rectangular plates have very similar characteristics as far as maximum Von-Mises stresses, maximum strain and maximum displacement are considered.
• The plate with 3 holes has an almost negligibly higher displacement value by the order of 0.00005 mm.
• The plate with one hole experiences more stresses and this leads us to conclude that the increased number of holes reduces stress concentration .
