摘要: This study aimed at measuring the static coefficient of friction (mu) between bone and skeletal muscle tissues in order to support finite element (FE) modeling orthopaedic rehabilitation research, where such contact conditions need be defined. A custom-made meter (FM) that employs load cell motion-controlled loading arm a materials testing machine was designed for this study. The FM used measure mu fresh ulna bones extensor muscles surrounding ulna, which were harvested from five young adult pigs. Mean bone-muscle 0.36 0.29, decreased with increase loads applied on (p<0.05) plateaued mean approximately 0.3 exceeding 4 N. Hence, FE contacts through magnitudes kgs 10s-of-kgs are transferred, assuming appears appropriate.
