SmartBot, Volume 2, Issue 1, March 2026.Magnetic guidewires enable remote navigation in tortuous vasculature but often suffer from limited controllability, inefficient force transmission, and safety risks at bifurcations. This work presents a dual‐coil magnetic guidewire actuated by an external permanent magnet, enabling two steering modes with smooth curvature control and improved axial ...

Some Global Bifurcation Results for Elastic Plates [PDF]
, 1998 This paper is concerned with global bifurcation results of some buckling problems for thin elastic plates under von Kárman\u27s model. We consider these problems as applications of a general topological degree analysis for bifurcation of variational ...

Nonlinear Asymmetric Buckling of Truncated Spherical Shells [PDF]
, 1970 This paper is concerned with the theoretical study of buckling of truncated spherical shells. Sander’s nonlinear equations for deep shells are used and the equations of equilibrium are expressed in terms of displacements for spherical shells.

An analysis of dynamic stability of an elastic column
Theoretical and Applied Mechanics Letters, 2018 : By the Lyapunov direct method, dynamic stability of two conservative systems of finite degrees of freedom with one parameter is analyzed. Two Lyapunov functions are proposed for the two systems, respectively.

Localization in spherical shell buckling [PDF]
, 2019 International audienceThis paper addresses localization of the deformation due to buckling that occurs immediately following the onset of bifurcation in the axisymmetric buckling of a perfect spherical elastic shell subject to external pressure.

Bifurcations of a simplified buckling problem and the effect of discretizations
manuscripta mathematica, 1991 The author gives a detailed description of bifurcations on the trivial solution branch \(\{\) (0,\(\lambda\)); \(\lambda\in {\mathbb{R}}\}\) of a simplified buckling problem \(\Delta u+\lambda \sin u=0\) in \(\Omega =[0,1]\times [0,1]\), \(u=0\) on \(\partial \Omega\).

Enhanced sensitivity and tunability of thermomechanical resonance near the buckling bifurcation [PDF]
The high susceptibility of ultrathin two-dimensional (2D) material resonators to force and temperature makes them ideal systems for sensing applications and exploring thermomechanical coupling.

On the analysis of viscoplastic buckling [PDF]
, 1993 For elastic-viscoplastic structures the classical elastic-plastic bifurcation approach to inelastic buckling is not valid. Only an elastic bifurcation point exists in the el~tic-viscoplastic case, and the inelastic buckling behaviour is controlled by a ...

Effect of prebuckling and edge support on bifurcation buckling of torisphere, cylinder and cone [PDF]
, 2013 This paper considers the buckling behaviour of commonly used shell structures in the offshore and oil industry. Three types of shells subjected to external pressure were examined, and they are: (i) torispheres, (ii) circular cylinders and (iii ...
