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 ...
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. ...
Characteristics of Intermetallic Compounds in Dissimilar Friction Stir Welding: A Review
(
Springer New York LLC
