Solidworks beam deflection and MDSolids

In summary, Solidworks Simulation uses a non-linear finite element analysis approach that takes into account the actual geometry of the beam to calculate deflections, which may differ significantly from hand calculations or results from other software packages. Further reading material on finite element analysis can provide a deeper understanding of the fundamentals and how to use different software packages effectively.

Hi all

Sorry if this is in the wrong place...

I've been doing some beam deflections on a simply supported beam, with loads applied to the overhangs, and have used MDSolids, Hand Calculations and Solidworks.

My hand calculations match up with the results that I have got from MDSolids, however they differ significantly (in terms of percentage) when ran in Solidworks Simulation.
The difference is almost 50%, which equates to 0.15mm difference between the two. (I.E smaller deflection is 0.15mm and larger is 0.30) The larger deflection comes from the hand calculations and MDSolids.

I have used macaulys equation to calculate the bem deflection, which I have assumed doesn't actually take into account the geometry of the shape? It only takes into account the second moment of area, which for example, would be same for an 'I' beam or a piece of channel with equivalent dimensions.

Now, my question is this, How does Solidworks calculate deflection? Is it purely based on the second moment of area (which I think is called linear?), or does it also take into account the actual geometry of the beam (I think this is called non-linear?). If it is linear, then could I be getting a different deflection as a result of using fixed geometry for the supports? I have applied the loads in 3d, and ran the analysis in 3d. I have yet to try and treat the beam as a 2D model, as accessing Solidworks is particularly difficult for me at the moment. Or, is it as simple as I need to remodel the beam?

Also, if anyone out there can help me, would you please suggest some further reading material please?

Many thanks

for your time! :)</code>Solidworks Simulation uses a non-linear finite element analysis approach to calculate deflections, which takes into account the actual geometry of the beam. The software also takes into account any additional elements such as supports, loads, etc. that are applied to the beam. Depending on the type of load being applied and the boundary conditions, the results can vary significantly from the hand calculations or MDSolids results. It is recommended to double check the results using different software packages or performing manual calculations.For further reading material, I would recommend looking at resources such as "Introduction to Finite Element Analysis Using MATLAB and Abaqus" by Saeed Moaveni or "Finite Element Analysis: Theory and Application with ANSYS" by Saeed Moaveni. These books provide an in-depth look at the fundamentals of finite element analysis and how to use different software packages to perform the analysis.
 

What is Solidworks beam deflection?

Solidworks beam deflection is a feature within the Solidworks software that calculates the amount of bending and deformation that occurs in a beam under a specific load. It takes into account factors such as material properties, cross-sectional area, and applied forces to accurately predict the deflection of a beam.

What is MDSolids?

MDSolids is a software program designed specifically for the teaching and learning of mechanics of materials. It includes modules for calculating beam deflection, stress and strain, and other common problems encountered in mechanics of materials courses.

How accurate are the results from Solidworks beam deflection and MDSolids?

The accuracy of the results from Solidworks beam deflection and MDSolids depends on the accuracy of the input data and assumptions made. These programs use well-established mathematical equations and principles to calculate deflection, so if the input data is correct, the results should be accurate.

Can Solidworks beam deflection and MDSolids handle different types of beams?

Yes, both Solidworks beam deflection and MDSolids have the capability to handle a variety of beam types, including cantilever, simply supported, and overhanging beams. These programs also allow for different loading conditions, such as point loads, distributed loads, and moments.

Do I need any prior knowledge to use Solidworks beam deflection and MDSolids?

Some basic knowledge of mechanics of materials and engineering principles would be helpful in using these programs, but they are designed to be user-friendly and intuitive. The programs also provide helpful tutorials and documentation to guide users through the process.
