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 ... -
