Comparison of Bending in Beams - FEA

COMPARISON OF BENDING OF BEAMS

Aim :

To undergo Finite element analysis of Cantilever beam of 3 types under a bending load using Solidworks Simulation.

Description :

3 cases of Cantilever Beams are considered and following cases are :

Conditions, Models & Mesh :

All measurements are in millimeters (mm)

Beams are considered to be Linear elastic isotrophic

Material : Alloy Steel

Length of beam : 400 mm in each case

Force : 1500N applied on the smaller face(i.e. 45mm face for case 1, 40mm face for case 2 and 45 mm face for case 3)

Mesh : Solid mesh of 6mm

Models :

Case 1 :

Case 2 :

Case 3 :

Stress Analysis :

Case 1 :

Case 2 :

Case 3 :

Displacement Analysis :

Case 1 :

Case 2 :

Case 3 :

Strain Analysis :

Case 1 :

Case 2 :

Case 3 :

Conclusion :

From the above Stress, Displacement, Strain analysis out of the 3 cases of beams, even though the 1st case beam has more realibility but it occupies more mass and considering the budget constraints, it's not a good choice. So, the Case 2 beam suits very much better for all the analysis with satisfactory results and fulfills the mass, cost constraints by reducing those aspects.
