Application of Differential Transform Method to Vibration Analysis of Damped Railway Bridge on Pasternak Foundation under Moving Train [PDF]

, 2016
In this paper, we used differential transform method (DTM) to analyse free vibration of a railway bridge, modelled as an orthotropic rectangular plate, supported by Pasternak foundation. The effect of damping was considered.

Pressure-induced spin-state transition of iron in magnesiow\"ustite (Fe,Mg)O

, 2017
We present a detailed theoretical study of the electronic, magnetic, and structural properties of magnesiow\"ustite Fe$_{1-x}$Mg$_x$O with $x$ in the range between 0$-$0.875 using a fully charge self-consistent implementation of the density functional ...

Mechanical Behavior of Multiple Edge‐Cracked Nanobeams by Taking Into Account the Multiple Cracks Effects

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

Bending analysis of nano-sized beam-elastic substrate systems: Unification of the stress-driven nonlocal model and Winkler-Pasternak foundation model

Results in Engineering
Nano- and micro-scale beam–substrate assemblies are key components of sensors, actuators, and flexible electronics, yet their mechanical responses deviate from classical elasticity because intrinsic material length scales govern their behavior.

Synchrotron Mössbauer spectroscopic study of ferropericlase at high pressures and temperatures [PDF]

, 2009
The electronic spin state of Fe^(2+) in ferropericlase, (Mg_(0.75)Fe_(0.25))O, transitions from a high-spin (spin unpaired) to low-spin (spin paired) state within the Earth’s mid-lower mantle region.
