3D models of anklebone and Achilles tendon were set up according to CT scan and software processing. Through the calculations on finite elements in the takeoff of back flop high jump, the stress-strain changes of Achilles tendon were obtained. At the last stage of beating the board, the tendon bears the highest tensile stress and the stress is concentrated on the 6cm area of calcaneal attachment nodules. This model can be used for biomechanical study on Achilles tendon, providing mechanical statistics for takeoff injuries and revealing some mechanical mechanism. |
