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 ...
A combined method to model dynamic recrystallization based on cellular automaton and a phenomenological (CAP) approach
(
MDPI AG
, 2018 , Article)
Titanium alloys with high stacking-fault energy show continuous dynamic recrystallization (CDRX) instead of discontinuous dynamic recrystallization (DDRX) during high-temperature deformation. During the CDRX mechanism, new ...
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. ...
The spectral and morphological studies of the conductive polyaniline thin film derivatives by the in situ copolymerization
(
Springer New York LLC
, 2017 , Article)
Thin film of copolymers of poly(aniline-co-2-iodoaniline) are obtained by in situ copolymerization of aniline and 2-iodoaniline as the startup monomers by chemical oxidation upon varying the molar feed to ratio of monomers ...
Impact of first-year seminar on student engagement, awareness, and general attitudes toward higher education
(
Emerald Group Publishing Ltd.
, 2018 , Article)
Purpose: This study intends to add to the existing body of literature on the impact of a newly implemented first year seminar in the College of Law and Business. The purpose of this paper is to evaluate the effects the ...
Modeling of student academic achievement in engineering education using cognitive and non-cognitive factors
(
Emerald Group Publishing Ltd.
, 2019 , Article)
The retention and success of engineering undergraduates are increasing concern for higher-education institutions. The study of success determinants are initial steps in any remedial initiative targeted to enhance student ...
From Zirconium Nanograins to Zirconia Nanoneedles
(
Nature Publishing Group
, 2016 , Article)
Combinations of three simple techniques were utilized to gradually form zirconia nanoneedles from zirconium nanograins. First, a physical vapor deposition magnetron sputtering technique was used to deposit pure zirconium ...
An investigation into hybrid carbon/glass fiber reinforced epoxy composite automotive drive shaft
(
Elsevier
, 2011 , Article)
This paper examines the effect of fiber orientation angles and stacking sequence on the torsional stiffness, natural frequency, buckling strength, fatigue life and failure modes of composite tubes. Finite element analysis ...
Energy absorption capability of composite hexagonal ring systems
(
Elsevier, Ltd
, 2012 , Article)
An extensive experimental investigation of inplane crushing of composite hexagonal ring system between platens has been carried out. Woven roving glass/epoxy hexagonal ring system with different angles and arrangement were ...
An experimental investigation into mechanical behavior of hybrid and nonhybrid composite semi-elliptical springs
(
Elsevier, Ltd
, 2013 , Article)
This study introduces a new composite semi-elliptical suspension spring by utilizing fiber reinforced composite strength in principal direction instead of shear direction. Three types of composites were tested, namely, ...
