Simscape multibody flexible bodies - get forces/stresses?

Hi, I'm using a flexible body in my simscape multibody model. I'm wondering if there is a way to get the overall forces/stress that the body sees/causes deformations?

Simscape Multibody models calculate the quantities necessary to determine the stress in the beam. While the beam models do not output stress quantities directly, you can use MATLAB or other methods to calculate stress (shear, tensile, compressive, etc.) at different locations along the beam using the formula best suited to your analysis.

Here is an example posted to the File Exchange that shows many of the basic steps to obtain necessary values and perform a calculation of the stress in a beam.

Below is a screenshot of the results produced by the example. Thanks to @Alberto Mora for sharing this example.

This is pretty cool, thanks for sharing. Unfortunately the beam we are using is a cirular annulus so I do not think the library will work for it. It seems like it only applies to rectangular beams. If I knew more I could probably edit this to meet my needs, but this is by no means my area of expertise.
