Viscoelastic Finite Line Contact of Thin Bonded Layered Solids of Low Elastic Modulus

Applied Sciences, 2020
A new finite element-based contact mechanics analysis of layered viscoelastic solids of low elastic modulus is presented. The methodology is based on the Maxwell viscoelastic element, with stress relaxation taken into account by the Prony series ...

Estimation of Power System Inertia Using Nonlinear Koopman Modes

, 2018
We report a new approach to estimating power system inertia directly from time-series data on power system dynamics. The approach is based on the so-called Koopman Mode Decomposition (KMD) of such dynamic data, which is a nonlinear generalization of ...

Scale‐Specific Viscoelastic Characterization of Hydrogels: Integrated AFM and Finite Element Modeling

Small, Volume 22, Issue 15, 12 March 2026.
An integrated multiscale approach reveals distinct viscoelastic responses of hydrogels across length scales. Combining AFM‐based nanoindentation, finite element modeling, and a novel analytical framework, this study enables accurate, scale‐specific mechanical characterization to guide the design of advanced biomaterials. Abstract Viscoelastic hydrogels

Prony's method under an almost sharp multivariate Ingham inequality

, 2017
The parameter reconstruction problem in a sum of Dirac measures from its low frequency trigonometric moments is well understood in the univariate case and has a sharp transition of identifiability with respect to the ratio of the separation distance of ...

Poroelastic Bulk Controls on Shear Localization in Fault Gouge During Earthquake Rupture: Insights From a Hybrid Numerical Framework

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Seismic ruptures that extend over kilometers along faults originate in shear zones only millimeters thick. We present a hybrid numerical framework coupling the spectral boundary integral method (SBIM) for the poroelastic bulk with a staggered‐grid finite difference method (FDM) for the fault gouge.

Titan's Plains Revealed: Evidence for a Layered Surface

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Undifferentiated plains are the most common terrain type on Titan, yet their composition and geologic history remain poorly understood. To better characterize their physical properties, we combined Cassini RADAR measurements from nadir altimetry and side‐looking SAR modes. We analyzed these data using radar backscatter models, finding that the

Oil Palm Fibers Micromechanics: Anisotropic Behavior

Journal of Natural Fibers, 2022
The anisotropic behavior of oil palm fibers (OPF) was investigated using finite element models, which were used to fit experimental data from stalk and mesocarp oil palm fibers under different tensile deformation modes.

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

Advanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.
