Instability by Extension of an Elastic Nanorod [PDF]
NanomaterialsThe static stability of an elastic, incompressible nanorod subjected to an extensional force is analyzed. The force is applied to a rigid rod that is welded to the free end of the nanorod.

Effects of constraint curvature on structural instability: tensile buckling and multiple bifurcations [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Bifurcation of an elastic structure crucially depends on the curvature of the constraints against which the ends of the structure are prescribed to move, an effect which deserves more attention than it has received so far.

Bifurcation analysis and phase diagram of a spin-string model with buckled states [PDF]
Physical Review E, 2017 We analyze a one-dimensional spin-string model, in which string oscillators are linearly coupled to their two nearest neighbors and to Ising spins representing internal degrees of freedom.

Controlling colloidal flow through a microfluidic Y-junction [PDF]
Communications PhysicsMicroscopic particles flowing through narrow channels may accumulate near bifurcation points provoking flow reduction, clogging and ultimately chip breakage in a microfluidic device. Here we show that the full flow behavior of colloidal particles through

Asymmetric-bifurcation snapping, all-or-none motion of Venus flytrap [PDF]
Scientific ReportsThe Venus flytrap is a carnivorous plant that catches insects by snapping rapidly and reopening slowly. To understand the mechanism underlying this asymmetrically reversible motion, a three-dimensional laser profiler was used to measure both static ...

On the method of calculation of buckling and post-buckling behavior of laminated shells with small arbitrary imperfections [PDF]
Acta Scientiarum Polonorum. Architectura, 2021 In the present paper the variant of computational methods of stability and initial post-buckling behavior of isotropic shells was generalized with respect to laminated composite shells. Using methods of the asymptotic analysis of the Timoshenko–Mindlin

Nonlinear Instability Behavior and Buckling of Shallow Arches Under Gradient Thermo-Mechanical Loads
Frontiers in Materials, 2022 This paper investigates the nonlinear behavior and buckling of shallow arches under gradient thermal and mechanical loading. The gradient temperature varies continuously along the thickness of the cross section of the arch but uniformly distributes over ...
