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.

Active Metamaterials with Tunable Shear Nonreciprocity and Nonlinear Dynamics. [PDF]
Adv Sci (Weinh)Active gear‐based mechanical metamaterials enable simultaneous control of translational and torsional stiffnesses by 30–100×, break shear reciprocity under positive versus negative loads, broadly tune resonant frequencies, and offer programmable dynamic responses.

Buckling Paradox And Anisotropic Plastic Plate Bifurcation [PDF]
Progress in Canadian Mechanical Engineering, 2018 Anisotropic elastic/plastic plate bifurcation is investigated. The pre-bifurcation loading consists of biaxial stresses along ξν axes parallel to the sides of a simply supported rectangular plate: ννξξσασ=,11α−≤≤. The ξν axes are at an angle βwith the xy principal axes of anisotropy.

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
