Helical buckling of Skyrme-Faddeev solitons [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Solitons in the Skyrme-Faddeev model on R^2xS^1 are shown to undergo buckling transitions as the circumference of the S^1 is varied. These results support a recent conjecture that solitons in this field theory are well-described by a much simpler model ...

Helical buckling of thin rods: FE modelling [PDF]
MATEC Web of Conferences, 2018 In this paper, we utilize the Finite Element (FE) method to model twisting of long thin rods and capture the bifurcation scenarios leading to heli- cal buckling and various further post-buckling states.

Twisted rods, helices and buckling solutions in three dimensions [PDF]
, 2013 The study of slender elastic structures is an archetypical problem in continuum mechanics, dynamical systems and bifurcation theory, with a rich history dating back to Euler's seminal work in the 18th century.

Helical buckling of actin inside filopodia generates traction. [PDF]
Proc Natl Acad Sci U S A, 2015 Significance Filopodia are essential membrane protrusions that facilitate cellular sensing and interaction with the environment. The mechanical properties of filopodia are crucial for their ability to push and pull on external objects and are attributed to actin dynamics. We confirm the presence of F-actin inside extended filopodia and reveal

Computational simulations of the helical buckling behavior of blood vessels. [PDF]
Int J Numer Method Biomed Eng, 2019 AbstractTortuous vessels are often observed in vivo and could hinder or even disrupt blood flow to distal organs. Besides genetic and biological factors, the in vivo mechanical loading seems to play a role in the formation of tortuous vessels, but the mechanism for formation of helical vessel shape remains unclear.

Helical Buckling in Filopodia [PDF]
Biophysical Journal, 2015 Filopodia are thin actin rich membrane protrusion that allow cells to interactively probe their environment by periodic protrusion and shrinkage interrupted by occasional kinks. Filopodial actin is thought to play a pivotal role in filopodial force transduction, bending, and rotation.

Stability of periodically supported slender structures and quantification of helix formation
Applications in Engineering Science, 2021 This paper investigates the configuration of periodically located cylindrical supports in order to impede buckling and/or failure of slender structures undergoing compression. This is done through parametric studies using a developed finite element model,
