Abstract
This pioneering research transforms theoretical nanomechanics into practical sports innovation by investigating the dynamic stability of rotating functionally graded material (FGM) structures at micro/nano scales. Through rigorous application of Hamilton's principle and energy methods combined with high-order nonlocal elasticity theories, we develop a comprehensive framework for optimizing sports equipment that experiences rotational motion and high-frequency vibrations. The study specifically targets next-generation athletic gear, including bicycle wheels, tennis rackets, golf club shafts, and running shoe components, where rotational dynamics and structural stability directly impact athlete performance, safety, and competitive advantage. Our numerical analysis reveals how size-dependent effects at small scales can be harnessed to create equipment with superior vibration damping, enhanced energy transfer efficiency, and unprecedented durability under extreme rotational loads. By integrating 2D-FGM architectures with nonlocal size effects, we demonstrate how equipment can be engineered to adapt dynamically to athletic movements, reducing injury risk while maximizing power transmission. This work establishes a new paradigm for sports equipment design that leverages cutting-edge material science to create adaptive, intelligent gear that responds to real-time athletic demands. The findings provide manufacturers with actionable insights for developing equipment that not only enhances performance metrics but also significantly improves athlete comfort and long-term joint health through optimized dynamic stability characteristics.
