The document describes analyzing a retaining ring to determine if it will yield under stress. A finite element analysis was conducted modeling the ring as a 2D shell with plane stress. Spring steel was initially used as the material but yielded under the expected stress. Beryllium copper was then selected, which did not yield. A mesh convergence study determined a seed size of 0.6 provided an accurate result without excess computation time. The analysis concluded beryllium copper was a suitable material and no design changes were needed.
