Secondary bifurcations in the buckling problem
Journal of Computational and Applied Mathematics, 1989 This paper considers the calculation of secondary bifurcations by purely numerical methods. A model problem of one nonlinear elliptic partial differential equation in two independent variables is treated. By means of continuation and local perturbation methods secondary branch solutions can be detected.

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation
Advanced Robotics Research, EarlyView.A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful

From Folding Mechanics to Robotic Function: A Unified Modeling Framework for Compliant Origami
Advanced Science, EarlyView.A geometry‐consistent DDG framework captures compliant origami deformation from rigid‐like folding to soft panel bending. By tuning crease and panel stiffness, bistable snap‐through responses transform into smooth monostable deformation, enabling programmable stability and robot‐scale locomotion.

Neuromorphic Devices and Computing for Sensing, Memory, and Control
Advanced Science, EarlyView.This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Symplectic method for the influence of surface effect on thermal buckling of graded porous nanobeams
Xibei Gongye Daxue XuebaoThe influences of surface effect on the thermal buckling behavior of graded porous nano-beams were analyzed. Based on the Grutin-Murdoch surface elasticity theory and Euler beam theory, the thermal buckling of graded porous nano-beams was studied by ...

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws
Advanced Intelligent Discovery, EarlyView.The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Influence of chirality on buckling of inextensible rings subject to dead loading
Vietnam Journal of MechanicsA variational approach is studied to understand buckling of inextensible rings made from chiral filaments and subject to dead loading. In opposite to previous literatures in which only in-plane bifurcation is allowed, i.e., the ring deforms only in its ...

Pressure-driven wrinkling of soft inner-lined tubes
New Journal of Physics, 2022 A simple equation modelling an inextensible elastic lining of an inner-lined tube subject to an imposed pressure difference is derived from a consideration of the idealised elastic properties of the lining and the pressure and soft-substrate forces.
