Investigation of Laser Ablation and Brush Pre‐Treatments for AlCu Cold Roll Bonding in Oxygen‐Free Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Free vibration analysis of beams on a Pasternak foundation using Legendre polynomials and Rayleigh-Ritz method.

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2017
A free vibration of Euler-Bernoulli and Timoshenko beams resting on a two-parameter elastic foundation of Pasternak type has been investigated. Rayleigh-Ritz method is employed to deduce the governing equation and the Legendre polynomials multiplied by a

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Piezoresistive Monitoring of Carbon Nanomaterial‐Reinforced Epoxy Composites Under Cyclic and Fatigue Loading: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Elastic settlement of ring foundations

open access: yesSoils and Foundations, 2015
AbstractIn this paper, numerical computations using the finite difference method are carried out in order to investigate the settlement of ring foundations resting over an elastic half space. The main goal of the present work is to introduce a closed form solution for calculating elastic settlement of ring foundations.

Flexural vibration and power flow analyses of axially loaded beams with general boundary and non-uniform elastic foundations

open access: yesAdvances in Mechanical Engineering, 2020
In this article, flexural vibration and its power flow of an axially loaded beam with arbitrary boundary and non-uniform elastic foundation are analyzed via energy principle in conjunction with Rayleigh–Ritz procedure.
