Asymptotic derivation of high-order rod models from non-linear 3D elasticity

no code implementations • 3 Dec 2020 • Basile Audoly, Claire Lestringant

A relaxation method is applied that holds the framed center-line fixed while relaxing the local degrees of freedom; it is asymptotically valid when the macroscopic strain and the properties of the rod vary slowly in the longitudinal direction.
