A Coupled Biomechanical-Smoothed Particle Hydrodynamics Model for Horse Racing Tracks
Frontiers in Bioengineering and Biotechnology, 2022 Distal limb injuries are common in racing horses and track surface properties have been associated with injury risk. To better understand how track surfaces may contribute to equine limb injury, we developed the first 3D computational model of the equine
