An optimization technique on ultrasonic and cutting parameters for drilling and deep drilling of nickel-based high-strength Inconel 738LC superalloy with deeper and higher hole quality
(
Springer-Verlag London Ltd
, 2016 , Article)
In this research work, an ultrasonic assisted drilling system is employed to apply both rotation and vibration to drill bits. The transducer horn transfers power very efficiently and changes tools effortlessly. The setup ...
Buckling and crushing behavior of foam-core hybrid composite sandwich columns under quasi-static edgewise compression
(
SAGE Publications Ltd
, 2019 , Article)
Buckling and crushing behavior of foam-core hybrid composite sandwich columns under edgewise compressive load is dealt in this study. Composite laminates with different stacking sequence configurations made of glass and ...
Transient response of porous inhomogeneous nanobeams due to various impulsive loads based on nonlocal strain gradient elasticity
(
Springer Netherlands
, 2019 , Article)
Transient vibration responses of a porosity-dependent functionally graded nanobeam under different impulsive loadings have been investigated in the context of non-local strain gradient theory. Three impulse loads of ...
Selection of alternative fuel taxis: a hybridized approach of life cycle sustainability assessment and multi-criteria decision making with neutrosophic sets
(
Taylor and Francis Ltd.
, 2021 , Article)
This study presents a combined application of hybrid life cycle sustainability assessment and multi-criteria decision-making, aiming to further advance an integrated sustainability assessment and decision-making for the ...
Penalized Conway-Maxwell-Poisson regression for modelling dispersed discrete data: The case study of motor vehicle crash frequency
(
Elsevier B.V.
, 2019 , Article)
Statistical modelling of road crashes has been of extreme interest to researchers over the last decades. Such models are necessary for the investigation of the opportunities for road safety improvement. The motor vehicle ...
Beneficial effect of shot peening on steamside oxidation of 300-series austenitic steels: An electrochemical study
(
Elsevier B.V.
, 2018 , Article)
The formation of a protective oxide ensures the good corrosion resistance of austenitic steels in high temperature steam. However after long-term interaction even the protective oxide may tend to exfoliate and cause ...
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. ...
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 ...
Design of thin wall structures for energy absorption applications: Enhancement of crashworthiness due to axial and oblique impact forces
(2013 , Article)
This paper describes a computationally aided design process of a thin wall structure subject to dynamic compression in both axial and oblique directions. Several different cross sectional shapes of thin walled structures ...
Composite sandwich structures for crashworthiness applications
(2007 , Article)
Fibre-reinforced polymer sandwiches are promising materials for reducing vehicle mass, thereby improving the fuel economics. Nonetheless, to fully explore these materials as the primary structures and energy absorbers in ...
