In this thesis, testing, modelling, and simulation studies of the Linear Shaped Charge (LSC) and Circular Linear Shaped Charge (CLSC) are presented. CLSC is an alternative design to the Flexible Linear Shaped Charge (FLSC). It contains a copper liner and metal housing which are designed and produced by considering the target profile. Then, a molten explosive (PBX-110) is cured inside the copper and housing, so the CLSC production is completed. By following this production method, different LSC and CLSC configurations are produced and tested for different target geometries. For each configuration, parameters that affect the penetration efficiency are investigated. Sufficient penetration results are obtained which can be an alternative to a FLSC penetration. Furthermore, an analytical and numerical model is developed to simulate the LSC and CLSC experiments. In the analytical model, a MATLAB code which calculates jet formation and target penetration is written by using theoretical formulas. In the numerical model, a 2D AUTODYN model is created. Jet formation and target penetration of the LSC and CLSC experiments are simulated. Reasonable results are obtained with the experiments for each of the analytical and numerical models.

Analytical solution and experimental verification of shaped charge jet penetration Gozubuyuk, Serkan; Yıldırım, Raif Orhan (2006-07-07) In the scope of this study a one dimensional shape charge code was developed using analytical and semi-empirical approaches. The penetration part of the code is based on the hydrodynamic theory of penetration. The code is capable of modeling and visualizing of shaped charge liner collapse, jet formation and target penetration. Factors affecting the penetration were investigated by utilizing the developed code. Since the code is based on the solution of some analytical expressions rather than the solution of...
DETRIMENTAL EFFECTS OF FLEXIBLE LINEAR SHAPED CHARGE (FLSC) TO NEARBY PLATES DUE TO VARYING BACKSPACE DISTANCE Bingol, C. G.; Yıldırım, Raif Orhan (2011-09-16) The objective of this study is to investigate the detrimental effects of a flexible linear shaped charge (FLSC) to variable thickness (3, 4 and 5 mm) Raex Ar 400 back plate and constant thickness (4.8 mm) Al-6061-T6 front plate due to varying backspace distance (0, 3, 6, 9, and 12 mm). A FLSC is used to cut both metallic and non-metallic material, quickly and efficiently. It is flexible and may be formed to produce cuts of many configurations, thereby making it particularly useful where more conventional cu...
Experimental evaluation of cable drum systems as linear motion sensors KILIÇ, ERGİN; Dölen, Melik; Koku, Ahmet Buğra (2011-04-15) This study evaluates cable-drum mechanisms as linear motion sensors for certain CNC applications. In this work, the dynamical attributes of a generic device are studied experimentally. The conducted research indicates that despite the significant traction force induced between the cable and its drum, small fluctuations in mechanism's speed yields a considerable (micro) slip at the interface.
Modeling of the Bosphorus exchange flow dynamics SÖZER, ADİL; Ozsoy, Emin (2017-04-01) The fundamental hydrodynamic behavior of the Bosphorus Strait is investigated through a numerical modeling study using alternative configurations of idealized or realistic geometry. Strait geometry and basin stratification conditions allow for hydraulic controls and are ideally suited to support the maximal-exchange regime, which determines the rate of exchange of waters originating from the adjacent Black and Mediterranean Seas for a given net transport. Steady-state hydraulic controls are demonstrated by ...
Investigation of effect of design and operating parameters on acoustophoretic particle separation via 3D device-level simulations Sahin, Mehmet Akif; ÇETİN, BARBAROS; Özer, Mehmet Bülent (Springer Science and Business Media LLC, 2019-12-16) In the present study, a 3D device-level numerical model is implemented via finite element method to assess the effects of design and operating parameters on the separation performance of a microscale acoustofluidic device. Elastodynamic equations together with electromechanical coupling at the piezoelectric actuators for the stress field within the solid parts, Helmholtz equation for the acoustic field within fluid, and Navier-Stokes equations for the fluid flow are coupled for the simulations. Once the zer...
