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

open access: yesMilan Journal of Mathematics, 2020
We 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.

On the new approach for the energy of elastica

open access: yesActa Scientiarum: Technology, 2018
In this work, we firstly describe conditions for being elastica in Minkowski space E41. Then we investigate the energy of the elastic curves and exploit its relationship with the energy of Bishop vectors belong to that elastic curves E41.

Morphological analysis of cells by means of an elastic metric in the shape space [PDF]

open access: yes, 2020
Shape analysis is of great importance in many fields, such as computer vision, medical imaging, and computational biology. This analysis can be performed considering shapes as closed planar curves in the shape space.

Nonlocal Elasticity Response of Doubly-Curved Nanoshells [PDF]

open access: yesSymmetry, 2020
In this paper, we focus on the bending behavior of isotropic doubly-curved nanoshells based on a high-order shear deformation theory, whose shape functions are selected as an accurate combination of exponential and trigonometric functions instead of the classical polynomial functions.

Characteristics of energy evolution during total stress-strain in rocks under uniaxial compression

open access: yesMeikuang Anquan, 2023
To study the energy evolution of rocks under uniaxial compression, uniaxial compression and uniaxial step loading and unloading tests were performed on granite, sandstone, and coal, and the stress-strain curves under different conditions were obtained ...

Fractal pattern formation at elastic-plastic transition in heterogeneous materials [PDF]

open access: yes, 2009
Fractal patterns are observed in computational mechanics of elastic-plastic transitions in two models of linear elastic/perfectly-plastic random heterogeneous materials: (1) a composite made of locally isotropic grains with weak random fluctuations in ...

Curves in the Lorentz-Minkowski plane: elasticae, catenaries and grim-reapers

open access: yesOpen Mathematics, 2018
This article is motivated by a problem posed by David A. Singer in 1999 and by the classical Euler elastic curves. We study spacelike and timelike curves in the Lorentz-Minkowski plane 𝕃2 whose curvature is expressed in terms of the Lorentzian ...

A Property of Euler's Elastic Curve

open access: yesElemente der Mathematik, 2000
Euler and Legendre found formulas for certain products of elliptic integrals. Legendre's proof is sketched, and Euler's method is generalized to prove a more general formula which may be interpreted as a property of a curve generalizing Euler's elastic curve.

Elastic strips [PDF]

open access: yes, 2010
Motivated by the problem of finding an explicit description of a developable narrow Moebius strip of minimal bending energy, which was first formulated by M. Sadowsky in 1930, we will develop the theory of elastic strips. Recently E.L.

Mechanical Characterization of Anchor under Uniaxial Compression Loading Conditions

open access: yesAdvances in Materials Science and Engineering, 2022
Bolt reinforcement technology plays an important role in supporting the construction of many engineering fields, and the uniaxial loading characteristics and behavior tests of anchors have great significance to the research and application of anchors ...
