Modelling and analysis of alternative face guard designs for cricket using finite element modelling

Cricket balls: construction, non-linear visco-elastic properties, quality control and implications for the game

“…The authors did not observe a reduction of the coefficient of restitution (COR) when increasing the impact speed to 6 m/s, as the COR remained constant at approximately 0.5. In addition, they suggest that the stiffness may increase with the deflection rate, a fact that has been proved by Subic et al [4].…”

“…In contrast to Subic et al [4], who found an exponential relationship between the loading velocity and the ball stiffness (Kookaburra Tuf Pitch), the model used in the present study is based on a power law, verified by stress relaxation. Thus, the relationship between the loading velocity and the ball stiffness follows a power law as well (Equation 15).…”

“…Raman Lamba was hit on the head when fielding, and subsequently suffered from a brain hemorrhage which eventually turned out to be fatal. Subic et al [4] demonstrated that the knowledge and FEA simulation of peak forces during impact are decisive for designing protective equipment.…”

“…power law). The ball model investigated by Subic et al [4], Kookaburra Tuf Pitch, and the Kookaburra Special Test, analysed in this study are identical according to the manufacturer [6], only the Tuf Pitch's leather cover is selected and finished for greater resiliance to abrasion.…”

“…Subic et al performed compression testing on the Kookaburra Tuf Pitch cricket ball at different deflection rates and found an exponential relationship between the loading velocity and ball stiffness [4]. These properties were required for developing a finite element model for impact between the ball and face guards, and for testing their designs.…”
