Investigation of Tire‑Tread Rubber Hysteretic Behaviour on Aggregates Through Experiments and Modelling

Journal of Tribology, EarlyView.
ABSTRACT Friction between tire rubber and pavement is governed by the interplay of hysteresis and adhesion yet their individual contributions remain difficult to quantify. This study addresses the long‐standing challenge by using reciprocating sliding tests by means of a tribometer and viscoelastic finite element modelling (FEM) to investigate rubber ...

Spring-dashpot models for the dynamics of a radially rotating beam with impact [PDF]

, 1990
In a previous study, experimental results for the dynamics of a radially rotating beam with impact were found to be in excellent agreement with simulation results using the momentum balance method (for impact modeling).

Viscoelastic Modeling of Stress Relaxation in Model High‐Performance Covalent Adaptable Networks

Journal of Polymer Science, EarlyView.
Covalent adaptable networks, often referred to as vitrimers, contain a certain fraction of bonds that are able to exchange with other bonds. The ability of this bond exchange to relax stress or result in flow of the material depends on the concentration and specific concentration of these bonds in ways that can be quantified.

NanoDMA and Nanoscratch Study of (Visco)‐Elastic and Plastic Behaviors of a Thin Film of a Molecular Spin Crossover Complex

Small, EarlyView.
Thin films of a molecular spin crossover complex are investigated across its thermally induced spin transition using quasi‐static and dynamic indentation techniques as well as nanoscratch experiments. When going from the low‐spin to the high‐spin state a sudden drop of elastic modulus is observed, but only a weak modulus relaxation occurs at the ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 17, Page 6124-6153, 10 December 2026.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Assessing Mesoscale Heterogeneities in Hard Carbon Electrodes Through Deep Learning‐Assisted FIB‐SEM Characterization, Manufacturing and Electrochemical Modeling

Advanced Energy Materials, Volume 16, Issue 42, 11 November 2026.
A combination of discrete and finite element method models for the current collector deformation and electrochemical performance analysis, respectively. The models are calibrated and validated with electrochemical and imaging data of hard carbon electrodes. These electrodes were manufactured with different parameters (slurry solid contents of 35 and 40

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3540-3560, November 2026.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

An Examination of the Reasons for, and Variability of, the Differences Between Response Spectra and Pseudo Response Spectra

Earthquake Spectra, Volume 42, Issue 4, November 2026.
For many decades, it has been common practice to overlook the differences between response spectra and pseudo response spectra. This practice stems from analyses indicating that the average difference between response spectra and pseudo response spectra is negligible for a viscous damping ratio of 5%, which is near‐universally adopted.
