Effect of thermoelastic damping in nonlinear beam model of MEMS resonators by differential quadrature method

Journal of Applied and Computational Mechanics, 2015
This paper presents a nonlinear model of a clamped-clamped microbeam actuated by an electrostatic load with stretching and thermoelastic effects. The frequency of free vibration is calculated by discretization based on the Differential Quadrature (DQ ...

Simulation of Locally Varying Residual Strains in 4D Printing

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Shape memory polymers (SMPs) are a class of materials capable of storing deformation in a programmed shape, which can be recovered when an external trigger, such as temperature, a magnetic field, or similar is applied. In the classical shape memory cycle, programming consists of successive heating, deformation and cooling steps. In combination

Modeling Nonlinear Acoustic Wave Propagation With Third‐Order Elastic Constants Using the Finite Element Method

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Due to the widespread usage of specialized piezoelectric actuators in various applications, accurate simulations have become key components of modern design processes. Although simulation tools for piezoelectric devices are widely available, nonlinear effects, which occur when exciting near resonance at elevated amplitudes, are often neglected

Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Moisture Effects on the Dimensional Stability of Bistable Carbon/Epoxy Laminates

Polymer Composites, Volume 47, Issue 19, Page 17449-17460, 10 October 2026.
Experimental and numerical approach for studying moisture effects on composite dimensional stability. ABSTRACT Bistable composite laminates are attractive because they can switch between two stable shapes without continuous energy input, enabling applications in morphing structures and energy harvesting devices.

Thermo‐Fluid‐Structural Coupling Analysis of Twin‐Screw Compressor Rotors Under Variable Operating Conditions

Applied Research, Volume 5, Issue 5, October 2026.
A validated thermo‐fluid‐structural coupling framework reveals that rotor von Mises stress exhibits a non‐monotonic trend with discharge pressure, reaching a minimum at 0.3 MPa (3000 rpm)—identifying a structurally optimal operating point that minimizes mechanical loading and extends fatigue life.

Surface‐Enhanced Raman Scattering‐Based Multimodal Medical Imaging in Cancer Diagnosis and Therapy Monitoring

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Surface‐enhanced Raman scattering (SERS) has emerged as a highly sensitive and specific technique for tumor imaging, owing to its narrow spectral features, resistance to photobleaching, and capability for multiplexed detection. However, its clinical translation remains limited by poor tissue penetration and the absence of intrinsic anatomical ...

A new methodology for thermoelastic model identification in composite materials using digital image correlation

, 2021
Local strain measurement techniques, such as strain gauges or extensometers, have been broadly utilized as input data source for thermoelastic effect model identification in fiber-reinforced polymers, despite their well-known high heterogeneity. This
