State‐of‐the‐Art Review of Vibration‐Based Health Monitoring of Piles
Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Vibration‐based health monitoring (VHM) has emerged as a promising technique for assessing the integrity of deep foundations by interpreting variations in dynamic response governed by soil–pile interaction. This review presents the theoretical background of foundation failure mechanisms, sensing technologies, and numerical approaches that underpin VHM ...

Advanced Theory and Simulations, Volume 8, Issue 10, October 2025.This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the

Natural Sciences, Volume 5, Issue 4, October 2025.The study presented investigates the thermo‐mechanical behavior of a sandwich structure with a tetrachiral‐shaped auxetic core. The geometric configuration, unit cell architecture, and the influence of the material length scale on the effective stiffness under temperature variation are illustrated.

International Journal of Mechanical System Dynamics, Volume 5, Issue 3, Page 535-563, September 2025.ABSTRACT This article investigates the nonlinear vibration behavior of porous multidirectional piezoelectric functionally graded nonuniform (PFGN) plates resting on orthotropic variable elastic foundations and subjected to hygrothermal loading. The sigmoidal law is employed to define the multidirectional gradation properties, incorporating porosity ...

Pasternak Model Formulation of Elastic Displacements in the Case of a Rigid Circular Foundation
Journal of Asian Architecture and Building Engineering, 2007 The classical Winkler model has often been used in many engineering fields. However, it has some shortcomings, because the adjacent displacements are discontinuous.

EFSA Journal, Volume 23, Issue 7, July 2025.Abstract This updated risk assessment evaluated evidence on potential adverse health effects of fluoride related to all sources of oral exposure as mandated by the European Commission. Fluoride benefit assessment was not included. Effects on the central nervous system, thyroid and bone were prioritised.

A Finite Element Study of the Bending Behavior of Beams Resting on Two-Parameter Elastic Foundation
Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2006 Although the Winkler’s model is a poor representation of the many practical subgrade or subbase materials, it is widely used in soil-structure problems for almost one and a half century.
