Finite element modelling of equestrian helmet impacts exposes the need to address rotational kinematics in future helmet designs

This paper compares the performance of four types of equestrian helmets in reducing the stress and strain in brain tissue using a combined FEM head model and FEM helmet model, which had been validated in previous studies. It also related the peak stress in brain to the linear head acceleration and rotational head acceleration. This work has demonstrated that the rotational kinematics, which is not considered in current helmet design standards, has a strong relationship to brain injury and should be considered in future standards. The output will improve the design standards for all types of protective helmets.
