“…Normally, COR is higher for particle with greater Young's modulus, due to the greater resistance to deformation, more elastic materials present higher COR. 14 Conversely, the target wall properties can also significantly affect the COR. Initially, the inherent properties of the wall material, be it metal, ceramic, or plastic, can dictate the energy transfer dynamics during collision.…”

“…The COR is defined as the decimal fractional value that represents the ratio of velocities before and after an impact of two colliding entities, which offers pivotal insights into the collision dynamics . Its significance is not only theoretical study but extends to practical applications, where understanding energy interactions during collisions can be the key to optimizing processes or designing solutions for challenges in various fields. − …”

Material Point Method is used to study the impact deformation of elastic-perfectly plastic spherical particles. A wide range of material properties, i.e. density, Young’s modulus and yield strength, are considered. The method is particularly suitable for simulating extensive deformation. The focus of the analysis is on linking the coefficient of restitution and the percentage of the incident kinetic energy dissipated by plastic deformation, Wp/Wi × 100, to the material properties and impact conditions. Dimensionless groups which unify the data for the full range of material properties have been identified for this purpose. The results show that when the particle deforms extensively, Wp/Wi × 100 and the equivalent plastic strain, are only dependent on the particle yield strength and the incident kinetic energy, as intuitively expected. On the other hand, when the deformation is small, Young’s modulus of the particle also affects both Wp/Wi × 100 and the equivalent plastic strain. Moreover, coefficient of restitution is insensitive to Young’s modulus of the material. Dimensionless correlations are then suggested for prediction of the coefficient of restitution, the equivalent plastic strain and Wp/Wi × 100. Finally, it is shown that the extent to which the particle flattens due to impact can be predicted using its yield strength and initial kinetic energy.
