(A) Shear relaxation modulus of Rheon compared with two elastomers and the shear modulus of EPS foam (40 g/l). (B) The helmet fitted with the viscoelastic components (CAD images published with kind permission by Dainese), (C) the components are composed of a small revolver and large revolver, fitted together, (D) the component designed to exhibit different deformation responses under compression and shear loading (CAD images published with kind permission by Rheon Labs).
