Modeling and optimization of the crushing behavior and energy absorption of plain weave composite hexagonal quadruple ring systems using artificial neural network
(
Elsevier Ltd
, 2019 , Article)
Composite structures are being increasingly utilized in the automotive industry for their lightweight and specific energy absorption capabilities. Recently, the Composite Hexagonal Quadruple Ring System (CHQRS) has been ...
Effect of fiber loading directions on the low cycle fatigue of intraply carbon-Kevlar reinforced epoxy hybrid composites
(
Elsevier Ltd
, 2019 , Article)
Effect of fiber orientation on tensile and low cycle fatigue of intraply hybrid composites was investigated. In this work, intraply carbon/Kevlar fabric/epoxy hybrid composites were tested for static and cyclic loadings ...
Nonlinear thermal buckling of axially functionally graded micro and nanobeams
(
Elsevier Ltd
, 2017 , Article)
In this study, the nonlinear thermal buckling of axially functionally graded (AFG) Euler-Bernoulli micro/nanobeams is analyzed. The Eringen's nonlocal elasticity theory is used to develop the governing equations of nanobeam ...
Comparison between microwave and conventional sintering on the properties and microstructural evolution of tetragonal zirconia
(
Elsevier Ltd
, 2018 , Article)
In this research, the comparison between microwave sintering and conventional sintering on the mechanical properties and microstructural evolution of 3 mol% yttria-stabilised zirconia were studied. Green bodies were compacted ...
Random number of units for K-out-of-n systems
(
Elsevier Inc.
, 2017 , Article)
This paper takes up the reliability and preventive replacement problems for a K-out-of-n system, where K is a stochastic parameter provided. Firstly, we consider the case when K is predefined as constant numbers as is done ...
Experimental and theoretical studies on axially crushed corrugated metal tubes
(
Elsevier Ltd
, 2018 , Article)
In this paper, crushing behaviors of tube with shallow and deep corrugation are experimentally and theoretically examined under axial loading condition. Three types of specimens were tested under quasi static axial loading. ...
Large eddy simulation of surge inception and active surge control in a high speed centrifugal compressor with a vaned diffuser
(
Elsevier Inc.
, 2016 , Article)
In this study, we present a numerical investigation of active surge control and performance improvement for an aero engine centrifugal compressor (NASA CC3) using self-recirculating bleed slots with different bleeding ...
Control charts for variability monitoring in high-dimensional processes
(
Elsevier Ltd
, 2019 , Article)
Monitoring process variability is associated with detecting changes in the covariance matrix of a multivariate normal process. Most monitoring methods estimate the sample covariance matrix and compare it with the in-control ...
Investigation of the tribological and biomechanical properties of CrAlTiN and CrN/NbN coatings on SST 304
(
Elsevier Ltd
, 2017 , Article)
This study examines the influence of thin layer coatings of CrAlTiN and CrN/NbN, deposited via physical vapor, on the biocompatibility, mechanical, tribological, and corrosion properties of stainless steel 304. The ...
Biomechanical design of a composite femoral prosthesis to investigate the effects of stiffness, coating length, and interference press fit
(
Elsevier Ltd
, 2018 , Article)
Traditionally, high stiffness hip prostheses are associated with aseptic loosening. Hence, the effects of stiffness, coating length, and interference press fit on load sharing and micro-movements are investigated for a ...
