Studies of impact dynamics of cricket balls have the potential of significantly improving the development of cricket equipment and also contribute to improving the player’s safety and performance. This work presents the development of a detailed multi-layer FE model for the structural analysis of cricket balls. The model was derived using experimental data obtained from tests developed for this purpose, including drop tests and high speed impact tests. The multi-layer, multi-material FE model was constructed using ABAQUS. Calibration of the model involves a multidisciplinary optimization technique. Comparison shows good agreement between experimental results and predictions from the refined model. Due to physical limitations, it was impossible to measure the material properties at high impact velocities. An alternative robust approach as detailed below was applied in order to indirectly determine the material properties. The material parameters under dynamic conditions were determined by modifying the initial material properties, obtained from the quasi-static test, to satisfy the results of experimental impact test of the inner core at different impact speeds. The entire process is based on a reverse engineering technique using modeFRONTIER (ESTECO, Italy), a computer program used for process integration and optimization which integrated ABAQUS and MATLAB to include FE simulation, results extraction, evaluation, and optimization.
