In this paper we are interested in studying the free motion of a hyperelastic body (also called swimmer) immersed in a perfect fluid. We derive the Euler-Lagrange equations from the Least Action Principle of Lagrangian Mechanics and prove that they are well-posed when the number of elastic modes is finite. The recourse to a strain energy density function in the modeling allows many different co...

Abstract. This work investigates the radial deformation of conductive magneto-hyperelastic solid cylinder subject to azimuthal magnetic field. It shows effect current density on solid. A simple magnetoelastic energy function is proposed for under consideration such that its purely elastic part corresponds strain well-known semilienar hyperelastic materials. The consequent magnetoelasticity fiel...

Knee articular cartilage exhibits complex mechanical behavior, even under high strain rates, which poses a challenge to developing accurate and efficient cartilage models. In particular, the tissue's stress–strain response is non-linear and the stiffness of the response is location-dependent. Hyperelastic models such as those of Alan Gent and others have increasingly found use in soft tissue bi...

BACKGROUND The biomechanical property of the periodontal ligament (PDL) is important in orthodontics and prosthodontics. The objective of this study was to evaluate the feasibility of measuring the biomechanical behavior of the periodontal ligament using micro-computed tomography (micro-CT). METHODS A custom-made apparatus measured the force and displacement of a porcine PDL specimen within t...
