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 ...
Kidney-on-a-chip: untapped opportunities
(
Elsevier B.V.
, 2018 , Article Review)
The organs-on-a-chip technology has shown strong promise in mimicking the complexity of native tissues in vitro and ex vivo, and recently significant advances have been made in applying this technology to studies of the ...
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 ...
Optimising stop-bands in periodic waveguides using genetic algorithms and wave finite element method
(
American Institute of Physics
, 2024 , Conference Paper)
In this paper, we propose using the wave finite element method and genetic algorithms to design periodic waveguide structures with optimal stop-bands. Instead of modelling waveguides using the standard finite element method, ...
