Elastodynamic analysis of a propagating finite crack in a micropolar elastic solid

Creator:: Han, Seog-young
Abstract:: A dynamic propagation of a finite crack of opening mode in a micropolar elastic solid was investigated. By using an integral transform method, a pair of twodimensional singular integral equations governing stress and couple stress was formulated in terms of the displacement transverse to the crack, macro- and microrotations, and...

Operation of a High-Temperature Oxidation Reactor for Thermochemical Energy Storage

Creator:: Ramsey, Owen C.
Abstract:: The cost of long-duration energy storage poses one of the most significant limitations on the penetration of renewables into power grids. Thermochemical energy storage has great potential to reduce this cost through the use of a reversible redox reaction pair that has a high enthalpy of reaction. The chemical nature...

Utilizing the thermodynamic properties of E85 to increase the specific efficiency of a high specific output single cylinder Formula SAE engine

Creator:: Duncan, Derek N.
Abstract:: Formula SAE is a collegiate engineering competition that has participants from around the globe. Of the 1000 points available throughout the event, 100 (10%) are dedicated to the fuel efficiency of the student built race cars. Competition rules allow either gasoline or E85, a mix of 85% ethanol and 15%...

Large-strain softening of aluminum in shear at elevated temperature

Creator:: Alhajeri, Saleh N.
Abstract:: Pure aluminum deformed in torsion (shear) at elevated temperatures reaches a broad "peak" stress and then undergoes about a 17% decrease in flow stress with deformation to roughly 1-2 equivalent uniaxial strain. Beyond this strain the flow stress is approximately constant. The sources for this softening are unclear. The suggested...

A Computational Fluid Dynamics Investigation of Hemolysis Potential in a Microfluidic Hemoperfusion Device Designed for Use in Sepsis Treatment

Creator:: Myers, Karl N.
Abstract:: The potential of red blood cell (RBC) and platelet damage was studied for a novel microfluidic hemoperfusion device currently in development at Oregon State University for use in treating sepsis. COMSOL 4.4's computational fluid dynamics (CFD) module was used to examine shear rate profiles in laminar, Newtonian blood flow throughout...

A Preliminary Methodology For Automating Functional Modeling

Creator:: Edmonds, Katherine N.
Abstract:: This thesis is the combination of two research publications working towards automating functional modeling. Functional modeling is an underutilized yet critical tool for concept generation and product design. Understanding the difficulty both novice and expert designers have in implementing functional modeling in their design process, this research sets out to...

Force and impulse control for spring-mass running

Creator:: Koepl, Devin N.
Abstract:: We present a novel control strategy for running which is robust to disturbances, and makes excellent use of passive dynamics for energy economy. The motivation for our control strategy is based on observations of animals, which are able to economically walk and run over varying terrain and ground dynamics. It...

Evaluation of failure diagnosis in conceptual design of mechanical systems

Creator:: Ruff, David N.
Abstract:: A methodology for improving quality and reducing life cycle costs of mechanical systems is described. The principal concept is that a system can be designed, in the conceptual stages, to be easier to diagnose for failures. To perform this, functional decomposition and form to function mapping are utilized both as...

A study of laser generated Rayleigh and Lamb waves in graphite/epoxy composites

Creator:: Park, Heeyong
Abstract:: The application of laser generated ultrasonics was first demonstrated in the mid-seventies and has shown good potential when applied to isotropic materials. However, its use with composite materials is still in the early stages of development. This study explores the potential for application of laser generated Rayleigh and Lamb waves...
