Analysis on a plate with a hole using Solidworks

Abstract :- To perform an analysis on a basic FEA problem i.e. plate with hole.

PROBLEM :-

Perform a static analysis on two models of plate with holes. You will have to create the model in Solidworks and perform the analysis.

The dimensions for the first case is as follows:

CASE 1

Length=300mm
Height=120mm
Thickness=30mm
Circular Hole at the center:
Diameter=60mm

The dimensions for the second case is as follows:

CASE 2

Length=300mm
Height=120mm
Thickness=30mm
Circular Hole at the center:
Diameter=60mm

Two holes of 30 mm diameter which are placed 90mm away from the central hole on both sides.

Apply a fixed relation to one of the short side of the plate and apply a force of 1000N on the other such that the plate is stretched.

Run the analysis and compare the results for stress, strain and displacement.

SOLUTION :-

CASE 1-

Stress

Strain

Displacement

CASE 2 -

Stress

Strain

Displacement

RESULT :-

	Yield Srength(N/mm^2)	Von Mises stress(N/mm^2)	Strain	Displacement(mm)
Case 1	6.204e+08	1.172e+06	4.235e-06	5.237e-04
Case 2	6.204e+08	1.137e+06	4.072e-06	5.658e-04

CONCLUSION :-

From above results it is coclude that,

In case 2 stress and strain developed in plate are less compared to case 1,because of in case 2 two extra hole around main hole acts as auxillary hole that reduce stress concentration factor.Due to that stress developed in case 2 are less ,also sress is directly proportional to strain hence strain are also less compared to case 1 .
