SolidWorks FEA (Varying Cross Section)

Click For Summary

Discussion Overview

The discussion revolves around the calculation of stresses in SolidWorks simulations, specifically in the context of finite element analysis (FEA) and its mathematical foundations. Participants explore the relationship between FEA and traditional beam analysis methods.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • Richard inquires about the method SolidWorks uses to calculate stresses in simulations, suggesting a possible connection to the second moment of area.
  • One participant questions Richard's understanding of how FEA works, implying that a grasp of the underlying mathematics is necessary for a proper discussion.
  • A later reply indicates that the author is currently studying FEA and believes that applying the mathematical principles learned will be more effective than relying solely on beam analysis.
  • Another participant seeks clarification on whether the discussion is about how FEA utilizes mathematics to solve problems or how FEA functions in general.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants express varying levels of understanding of FEA and its mathematical basis, with some exploring the topic further while others seek clarification.

Contextual Notes

There are limitations in the discussion regarding the assumptions about participants' prior knowledge of FEA and the specific mathematical methods involved in SolidWorks simulations.

Does anyone know how SolidWorks calculates the stresses for this simulation. Can anyone give me an idea, is it second moment of area? y/r = m/i?

Thanks
Richard.

Before we can answer this question, do you know how FEA works? (I mean the maths of it)
 
I'm halfway through a course on FEA at the moment, its becoming more obvious that using that mathematics will be the best way to solve the problem, rather than using beam analysis.
Sort of answered my own question.
Thanks anyway.
 
I mean how the FEA program uses maths to solve the problem? Or how FEA solves problems in general?
