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 ...
An adaptive thresholding-based process variability monitoring
(
Taylor and Francis Inc.
, 2019 , Article)
In high-dimensional processes, monitoring process variability is considerably difficult due to the large number of variables and the limited number of samples. Monitoring changes in the covariance matrix of a multivariate ...
Thermal stability and frequency-dependent electrical conductivity of poly(aniline-co-m-nitroaniline)
(
Institute for Ionics
, 2019 , Article)
Herein, we report the frequency-dependent AC conductivity of poly(aniline-co-m-nitroaniline)s which were synthesized by chemical oxidation of aniline and m-nitroaniline using ammonium persulfate as an oxidizing agent by ...
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 ...
