Discussion Overview

The discussion revolves around identifying the location of the highest stress in a tubular steel member that has been bent at a 90-degree angle with a specified center line radius. The focus includes considerations of loading conditions and the geometry of the bend.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the location of the highest stress in a bent tubular steel member, questioning whether it would be at the center of the curve or just outside.
  • Another participant suggests that if the bend is uniform, the maximum stress is likely at the inside radius in the center of the bend, but notes that this depends on the loading conditions.
  • A participant clarifies their inquiry by providing an image that better represents their interest in the stress distribution.
  • One participant asserts that the highest stress is likely on the inside at the end of the tube, where it experiences compression.
  • Another participant emphasizes that the highest stress will be in the region with the highest bending stress and seeks further ideas on identifying that location.

Areas of Agreement / Disagreement

Participants express varying opinions on the location of the highest stress, with no consensus reached on the exact point of maximum stress in the bent tubular member.

Contextual Notes

The discussion does not specify the type of load applied, which may influence the stress distribution. Additionally, the assumptions regarding the uniformity of the bend and the specific geometry of the member are not fully detailed.

I am wondering if anyone has any idea as to where the highest stress would be in a member that is tubular steel that has been bent 90degrees with a 3" center line radius. Would it be in the center of the curve or would it be just outside of the curve?

What kind of load is being applied to it? If it's a uniform bend its likely the maximum stress will be at the inside radius in the center of the bend, but it will depend somewhat on where and how the load is being applied.
 
Sorry I wasnt more specific. I have attached a picture that is more like what I am actually interested in. Its not exactly what I described in my first post, but hopefully it is pretty clear.

Highest stress is most probably on the inside on the end, where the tube is in compression.
 
The highest stress will be in the region with the highest bending stress. Any ideas on where the highest bending stress would be?
