Identification of hoof's material properties based on hyperelastic ogden

Finite element models have been used to study the mechanical responses of the equine hoof. The hoof is made up different tissues, including the sole, flexor and extensor tendons, frog, navicular bone, middle phalanx, hoof wall, distal phalanx, laminar junction, and digital cushion [1]. These tissues exhibit different material properties. In previous studies, to simplify the problem, these tissues have been considered to be linear elastic materials, although they show hyperelastic behavior [2]. In this study a sample hoof was taken for CT imaging and then modelled in CAD. Data available in the literature was used to achieve the parameter values of the hyperelastic Ogden model. This study is an important step to make hoof biomechanical models more accurate.
