Higher‐order and higher floating‐point precision numerical approximations of finite strain elasticity moduli

Summary Two real‐domain numerical approximation methods for accurate computation of finite strain elasticity moduli are developed and their accuracy and computational efficiency are investigated, with reference to hyperelastic constitutive models with known analytical solutions. The methods are high...
