Buckling and strength analysis of panels with discrete stiffness tailoring [PDF]

open access: yes, 2019
Continuous variation of stiffness across flat plates has been shown, theoretically, to improve buckling performance by up to 60%. However, steered fibre manufacturing methods cannot achieve the minimum radius of curvature required for improvement whilst ...

Buckling strength topology optimization of 2D periodic materials based on linearized bifurcation analysis

open access: yesComputer Methods in Applied Mechanics and Engineering, 2018
Low density cellular materials may offer excellent mechanical properties and find wide applicability in lightweight design and infill structures for additive manufacturing, yet currently existing material structures are still far away from their ...

Nonlinear dynamic intertwining of rods with self-contact [PDF]

open access: yes, 2007
Twisted marine cables on the sea floor can form highly contorted three-dimensional loops that resemble tangles. Such tangles or hockles are topologically equivalent to the plectomenes that form in supercoiled DNA molecules. The dynamic evolution of these

Symplectic method for the influence of surface effect on thermal buckling of graded porous nanobeams

open access: yesXibei Gongye Daxue Xuebao
The 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 ...

Pressure-driven wrinkling of soft inner-lined tubes

open access: yesNew 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.

Buckling Cascade of Thin Plates: Forms, Constraints and Similarity [PDF]

open access: yes, 1999
We experimentally study compression of thin plates in rectangular boxes with variable height. A cascade of buckling is generated. It gives rise to a self-similar evolution of elastic reaction of plates with box height which surprisingly exhibits ...

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

open access: yesAdvanced 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

An Analytical Study on the Thermal Post-Buckling Behaviors of Geometrically Imperfect FRC-Laminated Beams Using a Modified Zig-Zag Beam Model

open access: yesAerospace
An asymptotic analytical method is proposed to study the thermal post-buckling behaviors of fiber-reinforced composite (FRC)-laminated beams with geometric imperfections employing a modified zig-zag beam model.
