All rights reserved.High strength and low density requirement is the fundamental issue in aerospace industry. Many new engineering materials have been focused in recent years. After the 2ndWorld War, aluminum alloy (AA) 2050, (AA2050), which have low density, high fatigue resistance and excellent corrosion resistance, have become the focus of attention with their lighter weight, although they show high performance based on strength values as other using aluminum alloys in aerospace structural parts such as heavy plate applications, fuselage frames, wing skins and bulkheads. In addition to the strength values of materials used, when they show during machining, the reactions can change the desired strength values and geometrical dimensions. In this study feed rates, spindle speed, and radial depth of cut which directly affect the machining distortion, were optimized with the usage of the Box-Behnken experimental design method for AA2050. Based on the optimum cutting parameters obtained from the experimental design studies, materials were machined in a milling center with using a carbide end mill which have 20 mm diameter and 0.5 mm tip radius. Depending on the optimum parameters, cutting speed, material removal rate, and spending time are calculated for mass production terminology. Also, with the optimum parameters, on the machined part; geometric dimensioning and tolerance data such as perpendicularity, parallelism and flatness were examined, the distortion values on the workpiece were obtained. Based on the distortion analysis, a significant improvement has been achieved on the workpiece by optimization of cutting parameters.

Parameter Identification of Riveted Joints Using Vibration Methods
Altuntop, Elif; Aykan, Murat; Şahin, Melin (2015-02-05)
Rivets are widely used in several industries including aerospace, shipbuilding and construction. Aircraft components such as wings and fuselages are some examples of riveted structures. Accurate parameter identification of these joints is critical since excessive number of rivets is present in such structures. Furthermore, modeling structures with fasteners has always been a challenge since these members might show nonlinear behavior. In this study, the FEM of a continuous plate is constructed and modal tes...
Design Optimization of Variable Stiffness Composite Laminates Using Surrogate Models for Compliance and Buckling Load
İnci, Hasan; Kayran, Altan (2017-09-22)
Usage of composite materials in aerospace industry has never been so wide in our world. Starting from the development of composites, the analyses were only done for straight fiber composites. With the improved manufacturing capabilities, designers have the ability to design more complex shapes for composites, which allows more efficient structures. In the past two decades, variable stiffness (VS) composite laminates are introduced to the literature. Within these two decades, researchers working on VS concep...
Analysis and verification of a pyroshock test system
Küçükbayram, Anıl İsmail; Özer, Mehmet Bülent; Department of Mechanical Engineering (2021-2-03)
In the aerospace industry, systems, subsystems, and units are exposed toexplosive events during their lifecycle. Any explosive event creates shock in the structure, and it propagates until it is damped. This shock wave may be hazardous for some electronic and optical components. It may damage a component and cause failure in the equipment. For this reason, satellite equipmenthas tobe qualifiedto withstand all static and dynamic loads encountered during launch and operational life. Thus, one of ...
Dynamic failure of curved CFRP composite laminates under quasi static loading
Çöker, Demirkan (null; 2015-04-15)
In aerospace and wind energy industries, new advances in composite manufacturing technology and high demand for lightweight structures are fostering the use of composite laminates in a wide variety of shapes as primary load carrying elements. However, once a moderately thick laminate takes highly curved shape, such as an L-shape, Interlaminar Normal Stresses (ILNS) are induced together with typical Interlaminar Shear Stresses (ILSS) on the interfaces between the laminas. The development of ILNS promotes mod...
Prediction of input energy spectrum: attenuation models and velocity spectrum scaling
Alici, F. S.; Sucuoğlu, Haluk (Wiley, 2016-10-25)
Recent improvements in performance-based earthquake engineering require realistic description of seismic demands and accurate estimation of supplied capacities in terms of both forces and deformations. Energy based approaches have a significant advantage in performance assessment because excitation and response durations, accordingly energy absorption and dissipation characteristics, are directly considered whereas force and displacement-based procedures are based only on the maximum response parameters.
