Formulation and Solution of Curved Beams with Elastic Supports

open access: goldTehnicki vjesnik - Technical Gazette, 2018
This article presents the general system of differential equations that governs the behaviour of a curved beam, which can be solved by either numerical or analytical methods. The obtained solution represents the matricial expression of transference. The stiffness matrix is derived directly rearranging the transfer matrix.

Numerical Solution of Differential Equations of Elastic Curves in 3-dimensional Anti-de Sitter Space [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2023
In this paper, we aim to extend the Darboux frame field into 3-dimensional Anti-de Sitter space and obtain two cases for this extension by considering a parameterized curve on a hypersurface; then we carry out the Euler-Lagrange equations and derive ...

A Survey of the Elastic Flow of Curves and Networks [PDF]

open access: yesMilan Journal of Mathematics, 2021
AbstractWe collect and present in a unified way several results in recent years about the elastic flow of curves and networks, trying to draw the state of the art of the subject. In particular, we give a complete proof of global existence and smooth convergence to critical points of the solution of the elastic flow of closed curves in$${\mathbb {R}}^2$$

Bifurcation of elastic curves with modulated stiffness [PDF]

open access: yesEuropean Journal of Applied Mathematics, 2022
We investigate the equilibrium configurations of closed planar elastic curves of fixed length, whose stiffness, also known as the bending rigidity, depends on an additional density variable. The underlying variational model relies on the minimisation of a bending energy with respect to shape and density and can be considered as a one-dimensional ...

Geometric and topological approaches to shape variation in Ginkgo leaves

open access: yesRoyal Society Open Science, 2021
Leaf shape is a key plant trait that varies enormously. The range of applications for data on this trait requires frequent methodological development so that researchers have an up-to-date toolkit with which to quantify leaf shape. We generated a dataset

Confined Elastic Curves [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2011
We consider the problem of minimizing Euler's elastica energy for simple closed curves confined to the unit disk. We approximate a simple closed curve by the zero level set of a function with values +1 on the inside and -1 on the outside of the curve. The outer container now becomes just the domain of the phase field.

Elastic curves and phase transitions [PDF]

open access: yesMathematische Annalen, 2019
This paper is devoted to classical variational problems for planar elastic curves of clamped endpoints, so-called Euler's elastica problem. We investigate a straightening limit that means enlarging the distance of the endpoints, and obtain several new results concerning properties of least energy solutions.
