MWCNTs doped GFRPs drilling: crosscheck among holes obtained by alternative manufacturing methods
(Springer, 2021)
In this study, the holes of glass fiber reinforced polymer (GFRP) and multi-walled carbon nanotubes (MWCNTs) doped GFRP composite materials were drilled using abrasive water jet (AWJ), CO2 laser cutting, orbital drilling, ...
MALE UAV selection in interval Type-2 fuzzy sets environment
(IOS Press BV, 2022)
Unmanned Aerial Vehicles (UAVs) are increasingly used in the military field. Especially in recent years, UAVs have been a very effective instrument in gaining airspace superiority and military success. Many countries compete ...
Simultaneous swept anhedral helicopter blade tip shape and control-system design

The Theoretical Value for the Tip Radius of Cracks and Notches
(Kauno Technologijos Universitetas, 2022)
In this paper, an additional equation that can be used in conjunction with the Stress Intensity Factor is produced, enabling the determination of all critical fracture stresses, including tensile strength, from only one ...
Using the Stress Concentration Factor in Determining the Fracture Toughness
(Kauno Technologijos Universitetas, 2022)
This paper offers the use of stress concentration factor in determining the critical fracture stress and fracture toughness of polymeric composite materials at various crack length ratios. The stress intensity factor has ...
Obtaining the Fracture Resistance Curve Using the General Displacement
(Kauno Technologijos Universitetas, 2023)
In this paper, the energy release energy corre-sponding to the unit crack propagation obtained from the displacement-controlled load-displacement plot is equalized to the elastic energy release rate, and the variation of ...
The modified residual property model for fracture mechanics
(Kauno Technologijos Universitetas, 2023)
In this paper, the application requirement of the Residual Property Model based on the decrescent exponential function is reduced to only one mechanical test datum. For this, by using Creager , Paris's elastic stress field ...
Conceptual design and optimal sizing of a small unmanned aerial vehicle with fuel cell and battery-powered hybrid propulsion system by meta-heuristic algorithms based on energy consumption
(Taylor and Francis, 2023)
In this paper, a new conceptual design methodology for a hybrid propulsion system consisting of the battery and hydrogen fuel cells is presented based on the minimum energy consumption of the UAV. In this context, an ...
