Response of guyed offshore towers to stochastic loads in the presence of steady current

Creator:: Brynjolfsson, Sigurdur
Abstract:: The validity of the widely used stochastic linearization method for analysing the response of guyed towers to stochastic loads is investigated. The governing equations of a guyed tower have two main sources of nonlinearities, fluid-structure interaction and the restoring force of the cables. In this study, two models are considered....

Distortion-induced fatigue cracking of girder-to-crossbeam connection

Creator:: Aljutaili, Dhari S.
Abstract:: Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...

Design of a mechanically assisted dependent transfer mechanism for use on board commercial aircraft

Creator:: Gibson, Brenton D.
Abstract:: Business and recreation in the modern day world often include air travel as their cornerstone. Travelers who are disabled and wheelchair bound have to undergo a transfer process to board and deplane a commercial aircraft. This transfer process is typically done manually, with agents physically lifting the passenger who is...

A study of compression loading of composite laminates

Creator:: Berbinau, Pierre J.
Abstract:: The compressive behavior of continuous fiber composites is not as well understood as their tensile behavior because research and industrial applications have until recently focused on the latter. Furthermore, most theoretical and experimental studies on the compression of composites have examined the case of unidirectional specimens with fibers along the...

Nonlinear adaptive control of highly maneuverable high performance aircraft

Creator:: Cho, Sul
Abstract:: This thesis presents an effective control design methodology using a one-step-ahead prediction adaptive control law and an adaptive control law based on a Lyapunov function. These control law were applied to a highly maneuverable high performance aircraft, in particular, a modified F/A-18. An adaptive controller is developed to maneuver an...

Quality driven collaborative decision making for product development under the influence of trustworthiness

Creator:: Meier, Stefan
Abstract:: The focus of this study is the effective prioritization of customer requirements in collaborative product development. The CR priorities are often retrieved by questioning and interviewing targeted customers. But the targeted customer might not always be easily questioned, because they might not always be obvious or clearly known. If customers...

Cooling rate limitations in the diffusion bonding of large microchannel arrays

Creator:: Lingam, Gopi K.
Abstract:: A significant barrier to the diffusion bonding of large (i.e. 600 mm) microchannel devices is the large capital investment required to setup production. This large capital investment extends from long heating and cooling cycles leading to poor production capacities. Empirical studies in industry have shown that cooling rate is limited...

Evaluating the effectiveness of interaction strategies between product developer and supply chain using activity based modeling in environmental benign product design

Creator:: Wang, Bo
Abstract:: With growing concerns on environment impact of industrial product development, the product developers are seeking better solutions to achieve desired environmental benign requirements by the regulators and customers besides economic growth. During the last decade, some of the most successful product development companies (such as HP) have established their own...

Direct coupling of imaging to morphology-based numerical modeling as a tool for mechanics analysis of wood plastic composites

Creator:: Lin, Xiang
Abstract:: Polymeric composites reinforced with bio-materials have advantages over composites with synthetic reinforcements. Bio-based composites use low-cost and renewable reinforcements, have nonabrasive properties for machining, have improved damping characteristics, and have potential for energy recycling. However, the limited use of bio-based composites is because their mechanical properties are typically much lower...
