Variational Method and CZM‐Based FEM Mechanical Strength Assessment of Adhesively Bonded Hybrid Sisal‐Glass Reinforced HDPE Composite for Automobile Side Body Panel Application

Engineering Reports, Volume 8, Issue 2, February 2026.
Adhesively bonded steel‐to‐hybrid sisal–glass/HDPE joints were experimentally and numerically assessed using a variational method and CZM‐based FEM. Optimal overlap (10 mm) and adhesive thickness (0.5 mm) achieved peak shear stress of 32 MPa, confirming lightweight, sustainable automotive panel potential. ABSTRACT This study investigates the mechanical

Thermoelastic damping in parallel piezoelectric bimorph

Journal of Physics: Conference Series
Abstract Thermoelastic damping (TED) determines the upper limit of the quality factor. The accurate analysis of TED is critical for the design and research of microelectromechanical systems (MEMS). Therefore, the accurate analysis of electromechanical coupling, which is one of the main coupling forms in MEMS systems, on TED is also of ...

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.

Reduction of thermal fluctuations in a cryogenic laser interferometric gravitational wave detector

, 2012
The thermal fluctuation of mirror surfaces is the fundamental limitation for interferometric gravitational wave (GW) detectors. Here, we experimentally demonstrate for the first time a reduction in a mirror's thermal fluctuation in a GW detector with ...
