Derivation of a Curved Rod Model by Kirchhoff Assumptions

Using the so called Kirchhoff assumptions a special form of the equilibrium displacement for a three--dimensional curved rod-like elastic body is derived. The variational form of equilibrium equations of linearized elasticity written in terms of such special displacements reduces to a certain variational problem, called the curved rod model. This model is compared with the classical arch model.
