International Journal of Mechanical System Dynamics, Volume 5, Issue 1, Page 40-66, March 2025.ABSTRACT This research article introduces a high‐order finite element model based on the first‐order shear deformation theory to analyze the hygrothermal static responses of nanoscale, multidirectional nanofunctionally graded piezoelectric (NFGP) plates resting on variable elastic foundations. The study considers the material properties of these plates,

Surface waves in granular phononic crystals
, 2015 The existence of surface elastic waves at a mechanically free surface of granular phononic crystals is studied. The granular phononic crystals are made of spherical particles distributed periodically on a simple cubic lattice.

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 3, March 2025.Abstract This study investigates the doublet structural model for analyzing nonhomogeneous Euler mass sensor nanobeams, incorporating the concept of doublet mechanics alongside Bernstein polynomials (BPs). BPs serve as basic functions within the Rayleigh–Ritz method, facilitating conversional governing equations into a geikneralized Eigenvalue problem.

Analysis of the mechanical behavior of functional gradient porous plates on an elastic foundation
Scientific AfricanSummary: This study presents an in-depth analysis of the bending behavior of porous functionally graded material (P-FGM) plates resting on a Winkler–Pasternak elastic foundation. Two types of transverse loading are considered: uniform and sinusoidal. The

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 2, February 2025.Abstract In this study, the torsional vibration of a functionally graded viscoelastic nanotube has been carried out under viscoelastic boundary conditions employing nonlocal strain gradient theory. First, the equation of motion of the problem has been established using Hamiltonian principles and the Kelvin–Voigt viscoelastic model.

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 2, Page 684-697, February 2025.ABSTRACT By exploiting the stress‐driven model, within the Euler–Bernoulli beam theory, a novel nonlocal analytical model is proposed in order to simulate the mechanical behavior of multiple edge–cracked nanobeams by taking into account the multiple cracks effects. According to the present model, the nanobeam is split in correspondence with each of the
