An experimental investigation into crushing behavior of radially stiffened GFRP composite tubes
(
Elsevier Ltd
, 2014 , Article)
State-of-the-art studies of the crushing of composite tubes reveal different factors affecting their crashworthiness. Of those factors, the geometrical property of the tube is of great interest. In the current study, four ...
Mechanical properties, thermal stability and corrosion behavior of electrodeposited Ni-B/AlN nanocomposite coating
(
Elsevier B.V.
, 2018 , Article)
The present study focuses on the development of Ni-B alloy AlN nanocomposite coating employing a novel electrodeposition technique from citrate bath. The influence of incorporation of AlN particles on structure, thermal ...
Numerical and wind tunnel investigation of Hot Air Recirculation across Liquefied Natural Gas Air Cooled Heat Exchangers
(
Elsevier B.V.
, 2018 , Article)
Air Cooled Heat Exchangers (ACHE)s are used for heat rejection in Liquefied Natural Gas (LNG) plants. Their thermal performance decreases under elevated ambient temperatures and windy conditions as exhaust air recirculates ...
Crushing behavior of a unit cell of CFRP lattice core for sandwich structures’ application
(
Elsevier Ltd
, 2017 , Article)
Sandwich structures made of composites are designed mainly for higher and efficient load capacity. Mostly, the use of composite materials in lattice core sandwich structures is limited to the face sheet; whereas, the core ...
Collapse behavior of thin-walled corrugated tapered tubes under oblique impact
(
Elsevier Ltd
, 2018 , Article)
Thin-walled structures are used in safety applications such as automotive vehicles and locomotives because of their efficient energy absorption, light weight, and reduced manufacturing cost. The performance of these ...
Replacement policies for a parallel system with shortage and excess costs
(
Elsevier Ltd
, 2016 , Article)
It has been assumed in most maintenance models that (i) the number of units for a parallel system can be predefined precisely, (ii) maintenance cost after failure should be avoided, and (iii) age replacement can always be ...
Optimization of Viscoelastic Metamaterials for Vibration Attenuation Properties
(
World Scientific
, 2020 , Article)
Metamaterials (MMs) are composites that are artificially engineered to have unconventional mechanical properties that stem from their microstructural geometry rather than from their chemical composition. Several studies ...
Self-organized TiO2 nanotube layer on Ti–6Al–7Nb for biomedical application
(
Elsevier B.V.
, 2015 , Article)
In the present study, a self-organized nanotube TiO2 layer on Ti–6Al–7Nb was fabricated. The influence of acidic electrolytes including glycerol (G) and ethylene glycol (EG) on the anodization, microstructural features and ...
Constitutive analysis for the quantification of hardness decay in a superlattice CrN/NbN hard-coating
(
Elsevier B.V.
, 2015 , Article)
In the present study, a constitutive analysis of the evolution of the mechanical response of a CrN/NbN superlattice coating exposed to high temperature has been performed. Parametric approaches were used to obtain a single ...
Large eddy simulation of surge inception and active surge control in a high speed centrifugal compressor with a vaned diffuser
(
Elsevier
, 2016 , Article)
In this study, we present a numerical investigation of active surge control and performance improvement for an aero engine centrifugal compressor (NASA CC3) using self-recirculating bleed slots with different bleeding ...
