Electrospinning of Super Tough Nylon 6,6 Fibers and Their Use in Layered Composites
(Fen Bilimleri Enstitüsü, 2023)
Despite their obvious advantages in applications that require a high strength-to-weight ratio, delamination problems in layered composite structures continue to be a major drawback. Interleaving the layers with films or ...
Investigation of Bending Characteristic of 5XXX – Series Aluminum Alloys
(Fen Bilimleri Enstitüsü, 2023)
In this study, strains and fraction formation which occur in the parts was examined by creating a bending simulation in the MSC.Marc finite element analysis program for En AW-5083-H321 series of aluminium which are more ...
A Novel Constant Force Compliant Gripper Design
(Fen Bilimleri Enstitüsü, 2023-04)
The aim of this thesis is to design a novel constant-force compliant gripper mechanism. The design is a monolithic holding mechanism which is fixed on one side and free on the gripper side. The mechanism has four compliant ...
Investigation of Micro-Scale Stress Distributions and Concentrations In Hybrid Fiber-Reinforced Composites
(Fen Bilimleri Enstitüsü, 2023-01)
Hybrid composite materials are a specialized version of composite materials that constitute at least two different fiber materials. Hybrid composites are promising materials for various engineering applications. These ...
Artificial Neural Network-Based Design Tool for the Horizontal Stabilizer of a Helicopter
(Fen Bilimleri Enstitüsü, 2022)
Designing a helicopter is quite difficult and complex. Every decision made in the preliminary design phase seriously impacts the further design phases of a helicopter project. Therefore, it is vital to initially make the ...
Effect of Hot Extrusion, Annealing and Warm Rolling on the Functional Fatigue Behaviors of Nitihf High Temperature Shape Memory Alloys
(Fen Bilimleri Enstitüsü, 2023)
High temperature shape memory alloys (HTSMAs) have a wide range of application in aerospace, automotive and petroleum industries as high temperature actuators. NiTiHf HTSMAs are the most potential alloys compared to the ...
Robust Autolanding System Design for a Combat Aircraft on the Ground
(Fen Bilimleri Enstitüsü, 2023-02-01)
Within the scope of this thesis, a 6-degree-of-freedom model of a combat aircraft is
created. Apart from the flight dynamics, landing gear dynamics on the ground are also
modeled. After that, a robust autolanding system ...
Hydrodynamic Optimization of the Submarine with a Fully Parametric CAD Model
(Fen Bilimleri Enstitüsü, 2023-02)
This study was conducted to compare the performance of four different optimization
studies that can be done to reduce the drag force that a submarine is exposed to in fully
submerged conditions. The submarine used in the ...
Broadband and High Frequency Piezoelectric Energy Harvesting System With Curved Panels For Passive Vibration Isolator
(Fen Bilimleri Enstitüsü, 2023-02-01)
In military aircrafts, random vibration occurs with high amplitude in broad frequency
spectrum. High vibration profiles, which affecting electronic units, can cause fatigue over
time and damage mechanics and electronic ...
Modelling and Analysis of Legged Robots with Temporary Flight Capabilities
(Fen Bilimleri Enstitüsü, 2022)
The high obstacle-crossing potential of legged robots has made them a widely studied subject. However, the obstacles that can be overcome are generally proportional to the length of the legs. And any study, that states a ...
