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

Aerospace
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.

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.

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 Mechanics
A 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 ...

Material‐Based Intelligence: Autonomous Adaptation and Embodied Computation in Physical Substrates

Advanced Intelligent Systems, EarlyView.
This perspective formulates a unifying framework for Material‐Based Intelligence (MBI), defining the physical requirements for materials to achieve embodied action, active memory and embodied information processing through intrinsic nonequilibrium dynamics. The design of intelligent materials often draws parallels with the complex adaptive behaviors of

On the bifurcation analysis of thin multilayer structures by the Asymptotic Numerical Method [PDF]

Journal of Theoretical, Computational and Applied Mechanics
This paper focuses on the stability analysis of multilayer thin shells using the asymptotic numerical method (ANM) combined with Padé approximants. This technique is highly effective for solving nonlinear problems due to its high-order algorithm that ...

Direct numerical simulations of three-dimensional surface instability patterns in thin film-compliant substrate structures

Scientific Reports, 2021
A comprehensive numerical study of three-dimensional surface instability patterns is presented. The formation of wrinkles is a consequence of deformation instability when a thin film, bonded to a compliant substrate, is subject to in-plane compressive ...

Bifurcation analysis and phase diagram of a spin-string model with buckled states [PDF]

, 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.

Liquid Jetting‐Based Miniature Robotic Navigation in Confined Fluidic Spaces

Advanced Intelligent Systems, EarlyView.
We introduce a new class of liquid‐jetting‐based miniature robots (JetBots) ranging in size from mm‐to‐cm, featuring a unified approach in design, fabrication, and actuation. They demonstrate fast locomotion (30.3 cm/s), rapid steering (648.8°/s), and diverse functions, such as puncturing soft materials and unlimited cargo sampling and delivery, paving

Mode Interaction in Wide Plate with Closed Section Longitudinal Stiffeners Under Compression

Engineering Transactions, 1987
Interaction of nearly simultaneous buckling modes in the presence of imperfections is studied. The investigation is concerned with an infinitely wide plate having thin-walled longitudinal stiffeners of trapezoid cross-section under uniform compression ...
