Out-of-plane bending stress on an I-beam

Click For Summary

Discussion Overview

The discussion revolves around the derivation and understanding of the out-of-plane bending stress equation for a curved I-beam, specifically the equation sigmaR = tFlange * sigmaNormal/(radius of curvature). Participants are exploring the theoretical underpinnings of this equation.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant presents the out-of-plane bending stress equation and expresses a desire to understand its derivation.
  • Another participant prompts for clarification on what is meant by "out of plane," suggesting the need for a definition of the relevant plane.
  • A participant indicates they are working on a solution and may have made progress in understanding the equation.
  • Another participant inquires about the progress made, noting that some information shared previously is not clearly readable.

Areas of Agreement / Disagreement

The discussion does not appear to have a consensus, as participants are still seeking clarification and understanding of the concepts involved.

Contextual Notes

There are limitations regarding the definitions of terms used, particularly "out of plane," which may affect the clarity of the discussion. Additionally, some mathematical steps or assumptions underlying the equation remain unresolved.

TL;DR
out of plane bending stress
I know the out of plane bending stress equation for a curved I beam but I am trying to figure out where it came from. sigmaR = tFlange * sigmaNormal/(radius of curvature)

You need to define what you are thinking about as "out of plane." This is out of what plane?
 
I think I may have figured it out. Let me finish what I have on paper
