Dynamic response of metal foam FG porous cylindrical micro-shells due to moving loads with strain gradient size-dependency
(
Springer Verlag
, 2019 , Article)
The dynamic characteristics of functionally graded (FG) metal foam cylindrical micro-scale shells in contact with a moving load will be analyzed thorough this paper accounting for strain-gradient size-dependency. In the ...
Dynamic response of functionally graded graphene nanoplatelet reinforced shells with porosity distributions under transverse dynamic loads
(
Institute of Physics Publishing
, 2019 , Article)
This article investigates forced vibrational characteristics of a porous nanocomposite shell reinforced by graphene platelets (GPLs) under radial dynamic loads. Material properties of the shell dependents on uniform and ...
Poly(aniline-co-3-aminophenol): enhanced crystallinity and solubility
(
Springer Verlag
, 2019 , Article)
An improvement of physiochemical properties such as solubility, crystallinity, and the surface morphology of the copolymer have been achieved via the in-situ copolymerization of the monomers units using ammonium persulfate ...
Vibration of rotating functionally graded Timoshenko nano-beams with nonlinear thermal distribution
(
Taylor and Francis Inc.
, 2018 , Article)
The vibration analysis of rotating, functionally graded Timoshenko nano-beams under an in-plane nonlinear thermal loading is studied for the first time. The formulation is based on Eringen's nonlocal elasticity theory. ...
Kinematically admissible folding mechanisms for the progressive collapse of foam filled conical frusta
(
Springer Netherlands
, 2018 , Article)
In this paper, the progressive collapse of foam filled conical frusta is investigated analytically using four different kinematically admissible folding mechanisms with varied straight folds. Comparisons are made between ...
Poly(aniline-co-2-hydroxyaniline): towards the thermal stability and higher solubility of polyaniline
(
Springer Verlag
, 2019 , Article)
Here, we adopted a donor-acceptor criteria for charge transfer and synthesize the thermally stable copolymers of poly(aniline-co-2-hydroxyaniline) (PA-co-2-HA) by in-situ copolymerization method having different compositions. ...
Numerical and experimental investigation on corrugation geometry for metallic tubes under lateral loading
(
Trans Tech Publications Ltd
, 2018 , Conference Paper)
Energy absorption devices are being used to protect structures from severe damages and reduce injury to occupants during accidents. The integrated characteristics of crash absorption devices can be classified as high energy ...
Characteristics of Intermetallic Compounds in Dissimilar Friction Stir Welding: A Review
(
Springer New York LLC
, 2019 , Article Review)
In the present paper, mechanical and metallurgical characteristics of different dissimilar weldments fabricated by friction stir welding were investigated. Existence of lamellar composite structure within the stir zone in ...
Nonlinear free and forced vibrations of graphene nanoplatelet reinforced microbeams with geometrical imperfection
(
Springer Verlag
, 2019 , Article)
Nonlinear free/forced vibration of a functionally graded graphene nanoplatelet (GNP) reinforced microbeam having geometrical imperfection which is rested on a non-linear elastic substrate have been studied in the present ...
Evaluation of thermal history and defect in friction stir processing of as-cast magnesium AZ91
(
Trans Tech Publications Ltd
, 2018 , Conference Paper)
Friction stir processing (FSP) is a thermos-mechanical process for modifying the microstructural and material properties of metals. FSP also can be used for mechanical alloying and producing metal matrix composites. Due ...
