Web27 Jan 2024 · Rods are filamentary structures capable of two main reversible deformations causing large displacements, namely, bending and twist. Classically, they are modeled as long, thin elastic bodies defined by a central curve and acted upon by external loads [ … WebCosserat-type rod theories are based on the consideration of a rod base curve as a deformable directed curve, that is a curve with attached deformable or non-deformable (rigid) vectors (directors), or based on the derivation of one-dimensional (1D) rod equations from the three-dimensional (3D) micropolar (Cosserat) continuum equations.
On the dynamics of rods in the theory of Kirchhoff and Clebsch
WebThe rod, initially straight, is assumed to behave as a one-dimensional elastic body according to the special Cosserat theory of rods. Although readily extendable to encompass effects of shear and extensibility, the present reformulation is, for the sake of brevity, restricted to rods that can undergo large deformations in space by experiencing bending and torsion.
