Nonlinear Weakly Curved Rod by Γ-Convergence [PDF]
Journal of Elasticity, 2011 We present a nonlinear model of weakly curved rod, namely the type of curved rod where the curvature is of the order of the diameter of the cross-section. We use the approach analogous to the one for rods and curved rods and start from the strain energy functional of three dimensional nonlinear elasticity and do not presuppose any constitutional ...

Template guided versus freehand rod bending in spinal deformity surgery: a feasibility study [PDF]
Scientific ReportsSpinal deformity correction relies on osteotomies and precisely contoured rods, which are critical for restoring sagittal alignment. Inaccurate rod bending may compromise alignment and increase the risk of junctional failure.

Derivation of a Curved Rod Model by Kirchhoff Assumptions
ZAMM Zeitschrift Fur Angewandte Mathematik Und Mechanik, 1999 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

Natural and forsed osculations of pipelines in contact with the Wincler medium [PDF]
E3S Web of Conferences, 2023 In this paper, the pipeline is modeled as a curved rod in contact with the Winkler medium. Linear oscillations of a curved viscoelastic rod lying on the Winkler base are considered.

Dynamic instability of vibrations of thin-wall composite curvorine viscoelastic tubes under the influence of pulse pressure [PDF]
E3S Web of Conferences, 2020 In this paper the results of a study of the dynamic characteristics of thin-walled composite curved viscoelastic pipes under the influence of internal pulsating pressures is presented. The relationship between stress and strain is described by the Aviary

Improving the Efficiency of Curved Wells’ Operation by Means of Progressive Cavity Pumps
Energies, 2022 This paper proposes a solution to the problem of improving the reliability of the operation of progressive cavity pump units in deviated and directional wells. High dogleg severity significantly contributes to rod breakage; rods often break close to the “

Asymmetric peptidoglycan editing generates cell curvature in Bdellovibrio predatory bacteria
Nature Communications, 2022 Cells of the predatory bacterium Bdellovibrio bacteriovorus, which invades and replicates within the periplasm of other bacteria, have a characteristic curved rod shape. Here, Banks et al.
