Interesting paper by @jedbrown et al.

For computational mechanics/physics, if you code by just punching in the equations from the textbooks directly, the physics should work, but computationally the way you evaluate the quantities may be unstable. This paper lists some recipes to avoid these.

Mostly small strain problem, but still feels icky to leave in.

Saw a paper on a soft robotic star thing, and had to check. Yep I can confirm, it looks like it can grab things.

Here is a link to my fully parameterized implemention with #FEBio + #GIBBON: https://www.gibboncode.org/html/DEMO_febio_0085_soft_robotic_star_01.html

Indentation with a twist.

The rigid ball pushes into the rubber-like hyperelastic cube while also spinning. Friction then transfers torsional forces to the cube as well.
