Dataset of Microstructural and Dynamic Mechanical Properties of Compacted Loess Modified by Calcium Oxalate Crystals: Implications for Geotechnical Engineering in Loess Regions

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
Dynamic torsional shear tests and SEM/PCAS analysis were combined to characterize calcium oxalate crystal‐modified compacted loess. The dataset connects OA concentration, damping‐ratio behaviour, pore‐structure evolution and Pearson correlations, supporting micro–macro interpretation of chemically modified loess.

Connecting Bond Switching to Fracture Toughness of Calcium Aluminosilicate Glasses

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT Fracture toughness is a critical mechanical property of glasses, but a detailed understanding of its link to composition and structure is still missing. Here, focusing on the industrially important family of calcium aluminosilicate glasses, we measure the fracture toughness of two glass series using the single‐edge precracked beam method, one ...

Advanced Technologies for Characterizing and Detecting Battery Thermal Failure: A Review

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Illustration of advanced characterization techniques to predict battery thermal failure. ABSTRACT Energy storage is essential in accelerating the global transition toward clean and sustainable energy across various sectors. Lithium‐ion batteries (LIBs) have become increasingly significant for energy storage due to their high energy density, low ...

The Impact of Squeeze Film Damper and Support Nonlinear Forces on the Dynamic Response of High-Speed Flexible Rotors

Applied Sciences
To investigate the nonlinear dynamic response of rotor systems, a finite element model of the squeeze film damper-rotor system was established. With the Euler–Bernoulli beam rotor model, the nonlinear oil film forces of the squeeze film damper (SFD) and ...

A computational study on the influence of the delayed yielding phenomenon in magnetorheological oils on the steady state vibration and forces transmitted between the rotor and its frame

MATEC Web of Conferences, 2018
The theoretical analyses and practical experience show that only the damping effect adaptable to the current operating conditions makes it possible to achieve optimum performance of damping devices inserted in the supports of rotating machines.

Research on Dynamic Characteristic Coefficients of Integral Squeeze Film Damper

Machines
Integral squeeze film damper (ISFD) is a new type of structure that appeared on the basis of traditional squeeze film damper (SFD). Since the oil film in ISFD is a segmented structure without annular flow, the nonlinearity of the oil film force has been ...

An Analytical Turbulence Model for Squeeze Film Damper Short-Bearing Analysis

Applied Mechanics
This paper develops an analytical turbulence model for open-ended squeeze film damper (SFD) application. Prandtl’s mixing length theory is adopted to describe the momentum transfer within the damper for its thin-film turbulent flow.
