To compare the beams of different shapes using solidworks simulation

Aim: To compare the bending in the beam

Modeling :

for reference we have

using reference sketches we create the 3d model by extruding to a length of 400 mm

Analysis:

• choose the static analysis
• fix the one face of the beam as shown below
• apply the load of 1500N on the smaller face of the beam as shown in picture below
• give the finest mesh
• run the simulation

Mesh :

Loading condition :

Fixture as fixed support:

Results :

For case 1 :

For case 2:

For case 3:

Beam	Maximum von-mises stress	Maximum Displacement	Maximum strain
Solid Rectangular	9.421e+06	3.103e-02	3.087e-05
C shape	4.452e+07	3.307e-01	1.602e-04
I shape	2.565e+07	8.569e-02	8.876e-05

Conclusion:

From the results, we can say that for I shape the maximum von-mises are the lowest and for the c shape maximum displacement and maximum strain is lowest

but if we see with respect to material uses I and c beam are performing the best, where I beam gives lower stress posses very linearly displacement and not gets the twisted and also due to lower stress fatigue life can be more as compared to the c shape beam and where c shape beam is having the lowest displacement and strain so according to the situation both I and C beams can be used for the lower material

In the case of solid rectangular beam if strength and life is required and use of the material is not a problem then the rectangular-shaped beam is the best option
