Abstract
Finite element methods are applied to investigate the coefficient of restitution (COR) for the head of a golf club. ANSYS commercial finite element software is first applied to determine the COR of two different disc-shaped titanium impact surfaces. These values were then experimentally verified to validate the accuracy of the finite element model. Finally, ANSYS was applied to determine the COR for club heads according to USGA specifications to confirm the reliability of the finite element model. The model is then validated by comparison with experimental results. The model can not only reduce time needed for product design and experimental testing, but can serve as a basis for follow-up studies on ball flight trajectory.
