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 ...

Frequency-dependent electrical parameters and extracted voltage-dependent surface states in Al/DLC/p-Si structure using the conductance method
(Springer, 2023)
In the present work, a diamond-like carbon film (DLC) was electrodeposited on a p-Si substrate and was used to fabricate an Al/DLC/p-Si/Au metal/interlayer/semiconductor (MIS) Schottky diodes (SDs). The structural analysis ...
A monostatic RCS reduction study for an antenna in structural mode at X band
(Taylor and Francis, 2023)
In this paper, a radar cross-section (RCS) reduction of a microstrip antenna is investigated both experimentally and numerically. A traditional metal ground plane antenna and a bandstop frequency selective surface (FSS) ...
Pattern Shaping by Utilizing EBG Phase Response and Its Use in MIMO Radio Altimeter Antenna Design for Aircraft
(MDPI, 2023)
In this study, a novel pattern shaping technique is presented and applied to the uniquely designed multiple-input multiple-output (MIMO) radio altimeter antenna, acquiring area gain. Inspired by the behavior of the perfect ...
