Relativistic elasticity on an arbitrary spacetime is formulated as a Lagrangian field theory which is covariant under spacetime diffeomorphisms. This theory is the relativistic version of classical elasticity in the hyperelastic, materially frame-indifferent case and, on Minkowski space, reduces to the latter in the limit c → ∞. The field equations are cast into a first – order symmetric hyperb...

Hyperelastic materials are considered as special category of elastic solid because their nonlinear complicated constitutive laws. Due to large strain state, the behaviour such is often in finite deformation analysis. The behavior important. In this study, a novel meshless radial point interpolation method (RPIM) enhanced by Cartesian transformation (CTM), an effective numerical integration, pre...
