Experimental Analysis and Physics‐Based Analytical Model on Twisted and Coiled Artificial Muscles
Advanced Engineering Materials, EarlyView.Twisted and coiled artificial muscles made from silver‐coated nylon fibers are investigated through experiments and analytical modeling. The actuators achieve contractions up to 19.3% and specific work of 8 kJ kg−1, though efficiency remains limited (≈0.15%) by thermal losses.

High-frequency homogenization of zero frequency stop band photonic and phononic crystals
, 2013 We present an accurate methodology for representing the physics of waves, for periodic structures, through effective properties for a replacement bulk medium: This is valid even for media with zero frequency stop-bands and where high frequency phenomena ...

Challenges during Flash Lamp Annealing of Aerosol‐Deposited Barium Titanate Films
Advanced Engineering Materials, EarlyView.Aerosol deposition is used to rapidly deposit barium titanate films with thicknesses ranging from 2 to 16 μm at room temperature, eliminating the need for further densification. However, to recover the electromechanical properties, annealing is required, which limits the usage of temperature‐sensitive substrates.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Curve straightening and a minimax argument for closed elastic curves
Topology, 1985 The authors study the functional \(F=\oint k^ 2 ds\) (''total squared curvature'') on the space of smooth closed curves in \({\mathbb{R}}^ 3\) of fixed length. In particular they establish the Palais-Smale condition for F, so the gradient flow of F (''curve straightening'') is well-behaved.

A discrete framework to find the optimal matching between manifold-valued curves
, 2018 The aim of this paper is to find an optimal matching between manifold-valued curves, and thereby adequately compare their shapes, seen as equivalent classes with respect to the action of reparameterization.

Advanced Engineering Materials, EarlyView.This study investigates the fundamental mechanisms of a novel postweld treatment that significantly enhances fatigue performance through engineered residual stress (RS) states. A multiscale approach correlates tensile RS in the nanometallic multilayer coating with corresponding compressive RS in the steel substrate, thereby reducing localized stress ...
