Topology optimization of an anti roll bar of a heavy commercial truck for vehicle dynamics and durability
(The American Society of Mechanical Engineers, 2019)
Meeting the stringent requirements on fuel economy and emissions is still a challenge for automotive original equipment manufacturers (OEMs). In this study, we consider the light weighting opportunities of a heavy commercial ...
Design of bio-joint shaped knee exoskeleton assisting for walking and sit-to-stance
(Springer Nature, 2019)
In this study, a bio-joint shaped knee joint exoskeleton is presented. This design is meant for avoiding misalignment of the exoskeleton joint with the biological knee joint. For this purpose a cam mechanism has been ...
Critical review of the factors dominating the fracture toughness of CNT reinforced polymer composites
(IOP Publishing, 2019-01)
In this study, the main factors, which have substantial influence on fracture toughness of carbon nanotubes (CNTs)-based composites both at nano and macro scales, are discussed in detail. Based on the findings from the ...
Numerical and experimental analysis of the flow and transition of free synthetic jets
(IOP Publishing, 2019-04)
In this paper, flow characteristics and the transition of synthetic jets are investigated numerically and experimentally. The investigated synthetic jets have a dimensionsless stroke length L-0/d of 146 and 167, an U-0 of ...
Colloidal aluminum antimonide quantum dots
(American Chemical Society, 2019-07-09)
AlSb is a less studied member of the III–V semiconductor family, and herein, we report the colloidal synthesis of AlSb quantum dots (QDs) for the first time. Different sizes of colloidal AlSb QDs (5 to 9 nm) were produced ...
A comparative study for the junction temperature of green light-emitting diodes
(IEEE, 2019-10)
Solid-state lighting devices offer a wide variety of color options applicable for general and automotive lighting, various display systems, and a number of niche applications. As they get smaller, generated heat fluxes ...
Numerical and experimental analysis of a heat-pipe-embedded printed circuit board for solid state lighting applications
(Taylor & Francis, 2019-01-02)
Thermal management is one of the main issues for electronics cooling especially for tightly packaged PCBs that experience local heat generation. Thus, theoretical and experimental investigations have been conducted to ...
Topology optimization of constrained and unconstrained damping layers
(Canadian Acoustical Association, 2019)
Damping is an effective way of suppressing mechanical vibrations. Passive constrained and unconstrained layer damping patches are often used in the industry as damping solution for vibrations and acoustics problems. In ...
Cyclic deformation response of ultra-fine grained titanium at elevated temperatures
(Elsevier, 2019-05)
This study focuses on the high-temperature cyclic deformation response (CDR) of ultra-fine grained (UFG) titanium of commercial purity (grade 4) processed via equal channel angular extrusion as a severe plastic deformation ...
Effect of grain size on the very high cycle fatigue behavior and notch sensitivity of titanium
(Elsevier, 2019-12)
The very high-cycle fatigue performances of coarse-grained and ultrafine-grained titanium samples with different geometries at ambient temperature and various stress amplitudes were investigated. Severe plastic deformation ...
