I have added a couple of files for clarification. Also, I am plotting the radial stress as a function of the radius so the end result will include the variable "r".
\sigma_{r}=\frac{1}{tr}\int t\sigma_{\theta}dr
with a lower limit of a=inner radius, and upper limit of r=variable radius. For one, why is the thickness even included in the equation since it cancels anyway, and two, how do I treat the varying thickness of the cross-section? I have tried...
I have a u-shaped t-beam, and I am trying to calculate the radial stress where \theta=0 degrees. I have calculated \sigma\theta_{} but I am unclear on how to treat the varying thickness of the cross-section when integrating with respect to radius.
