Published Online: April 9, 2024
Fig. 9 FEM simulations of ( a ) the co-RCC, ( b ) the TRIVOT, ( c ) the TRIOVOT, ( d ) the QUADRIVOT, and ( e ) the HEXAVOT rotated by an angle of 20 deg. The bar legends give the von Mises stress in MPa. Insets show that the maximum stress is located at the center of the pivots.
