Erol, Fulya; Özgen, Gökhan Osman; Department of Mechanical Engineering (2014)
Viscoelastic materials are used extensively as a means of vibration control and isolation in many vibrating structures. For example, damping instruments utilizing viscoelastic materials such as surface damping treatments and vibration isolators fabricated of viscoelastic materials such as machinery mounts are widely used in automotive and aerospace industries for the purpose of vibration and noise control and isolation, respectively. Viscoelastic materials, as the name implies, behave in between a purely el...
Development of a data-driven forecasting tool for hydraulically fractured, horizontal wells in tight-gas sands
Kulga, B.; Artun, E.; Ertekin, T. (2017-06-01)
Tight-gas sand reservoirs are considered to be one of the major unconventional resources. Due to the strong heterogeneity and very low permeability of the formation, and the complexity of well trajectories with multiple hydraulic fractures; there are challenges associated with performance forecasting and optimum exploitation of these resources using conventional modeling approaches. In this study, it is aimed to develop a data-driven forecasting tool for tight-gas sands, which is based on artificial neural ...
Development of a structural design methodology for filament winding composite rocket motor case
Erturan, Yakup; Gürses, Ercan; Department of Aerospace Engineering (2019)
Filament winding pressure vessels have a unique place in many areas such as space and ground applications for decades. Filament winding pressure vessels are used in products where weight is very critical. In such applications, composite winding pressure vessels have significant advantages over metal pressure vessels due to their high specific strength. In this study, it is aimed to design and analyze composite rocket motor cases produced by the filament winding method. Within the scope of the study, the dom...
Development of a new hybrid damper for steel bracing systems
Shaban, Nefize; Caner, Alp; Department of Civil Engineering (2017)
A new hybrid energy dissipation device named as “Backbone Damper” is introduced. The device assembly is composed of two main components: a viscoelastic (VE) unit and an internal displacement amplification mechanism. Energy dissipation is generated through deformations of the VE unit and friction within the mechanism. The mechanism is designed to remain elastic. The effectiveness of the device is verified through numerical simulations of tests of full-size prototypes. A comprehensive three-dimensional solid ...
