Free and Forced Vibration Analysis of Stepped Circular Cylindrical Shells with Several Intermediate Supports Using an Extended Wave Method; a Generalized Approach

Latin American Journal of Solids and Structures
A combination of vectorial form of wave method (VWM) with Fourier expansion series is proposed as a new vehicle for free and forced vibration analysis of stepped cylindrical shells with multiple intermediate flexible supports.

Review of Gastrointestinal Capsule Robots: Materials, Actuation, Diagnostics, and Therapeutics

Advanced Science, EarlyView.
This review examines gastrointestinal capsule robots through a systems engineering lens, covering shell materials, actuation and localization strategies, diagnostic modalities, therapeutic interventions, and commercialization status. By mapping the complete technological chain from fabrication to clinical deployment, this work identifies critical gaps ...

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping

Advanced Science, EarlyView.
This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

Maximizing the Energy Output of Soft Electrohydraulic Generators

Advanced Science, EarlyView.
Many energy resources cannot be viably harvested with electromagnetic generators. This article evaluates the potential of soft electrohydraulic generators as an alternative approach for energy capture. An analytical model charts their operational limits and a rigorous experimental study results in new performance benchmarks with maximum specific energy

Stacking Pressure‐Driven Interfacial Dynamics in Anode‐Free Solid‐State Lithium Batteries

Advanced Science, EarlyView.
Using a three‐electrode setup, it is found that stacking pressure improves both anode and cathode interfaces but more effectively stabilizes the anode. Under low pressure, a sudden anode resistance rise indicates contact loss. Higher pressure delays this via Li creep and plastic deformation, maintaining interfacial contact.

Impact of Non-Stationary Pressure on a Cylindrical Shell with Elastic Core [PDF]

Учёные записки Казанского университета: Серия Физико-математические науки, 2016
The solution of the non-stationary problem for thin elastic circular cylindrical shell filled with an elastic medium under the influence of external non-stationary pressure has been obtained based on the superposition principle.

Giant Magnetic Purcell Effect Induced by High‐Order Mie Resonances

Advanced Science, EarlyView.
High‐order Mie resonances in dielectric spheres selectively amplify magnetic dipole emission from Eu3+ emitters, producing a giant magnetic Purcell effect. Localized emitters can efficiently access high‐order resonant modes, and the low‐loss TiO2 platform enables direct far‐field observation of the enhanced emission.

Analytical Calculation of Momentless Conical Shell with Elliptical Base

Structural Mechanics of Engineering Constructions and Buildings
Differential equilibrium equations of the momentless shell theory are very easily integrated in cases of cylindrical and right circular conical shells. Shells of zero Gaussian curvature defined in arbitrary curvilinear coordinates are more difficult to ...
