Title: A Semi-Quantitative Schlieren High-Speed Flow Diagnostic: Analysis of High-Pressure-Ratio, Overexpanded Planar Flow in Rocket Nozzles
Author: Thorsett-Hill, Karen
Date Created: 2012
Subjects--Topical: Mechanical engineering
Description: This work introduces a semi-quantitative schlieren (SQS) method which is used to qualitatively and quantitatively analyze complex, unsteady, compressible flows in a small, planar convergent-divergent nozzle. A basic schlieren system is used to ima...

Title: COMPARATIVE STUDY OF THE EFFECT OF IMPURITIES ON THE DUCTILITY OF TANTALUM AND TUNGSTEN BASED ON ATOMISTIC AND FIRST PRINCIPLES CALCULATIONS
Author: Pan, Zhiliang
Date Created: 2012
Subjects--Topical: Mechanical engineering, Materials science
Description: Tungsten and tantalum are neighbors in the Periodic Table of the Elements and, as refractory metals, both have very high melting points (tungsten: 3422oC, tantalum: 2996oC). However, the ductility of the two metals is quite different especially at...

Title: CONSTITUTIVE MODELING OF ALUMINUM FOAM AND FINITE ELEMENT IMPLEMENTATION FOR CRASH SIMULATIONS
Author: Bi, Jing
Date Created: 2012
Subjects--Topical: Mechanical engineering, Engineering
Description: In the past decades metallic foams have been increasingly used as filler materials in crashworthiness applications due to their relatively low cost and high capacity of energy absorption. Due to the destructive nature of crashes, studies on the pe...

Title: ENGINEERING OXYGEN TRANSPORT FOR IMPROVING CELL PERFORMANCE IN HEPATIC DEVICES
Author: Shi, Gengbei
Date Created: 2012
Subjects--Topical: Mechanical engineering, Biomedical engineering
Description: The bioartificial liver (BAL) advancing medical technology aims to provide temporary liver substitution for patients in dire need of liver transplants and also for drug development. Yet despite nearly fifty years of development, the approval for t...

Title: EXPERIMENTAL AND COMPUTATIONAL STRATEGIES FOR ENHANCING MASS TRANSPORT AND CRYOPRESERVATION OF BIOLOGICAL TISSUES
Author: Karthik Kumar, Balasubramanian
Date Created: 2012
Subjects--Topical: Mechanical engineering, Biomedical engineering
Description: A bioreactor is a large-scale engineered in vitro device that maintains a 3D arrangement of functioning cells for use in various bioengineering applications. The current work is focused on heat and mass transfer issues related to the bioreactor's ...

Title: EXPERIMENTAL INVESTIGATION OF TURBULENT WAKE STRUCTURES AND DYNAMIC COUPLING OF TANDEM LIFTING BODIES IN A HYDRODYNAMIC CHANNEL
Author: Hellman, Samuel
Date Created: 2012
Subjects--Topical: Mechanical engineering
Description: Two experimental studies are carried out on interacting tandem bodies in incompressible, turbulent flow and the design of a hydrodynamic water channel in which the studies are conducted is discussed. The water channel has a 1 m^2 test section, and...

Title: FULL-SCALE TESTING AND NUMERICAL MODELING OF A MULTISTORY MASONRY STRUCTURE SUBJECTED TO INTERNAL BLAST LOADING
Author: Zapata, Brian
Date Created: 2012
Subjects--Topical: Mechanical engineering, Physics, Civil engineering
Description: As military and diplomatic representatives of the United States are deployed throughout the world, they must frequently make use of local, existing facilities; it is inevitable that some of these will be load bearing unreinforced masonry (URM) str...

Title: Knee Joint Biomechanics after Anterior Cruciate Ligament Reconstruction
Author: Wang, Hongsheng
Date Created: 2012
Subjects--Topical: Mechanical engineering, Biomechanics, Biomedical engineering
Description: Anterior cruciate ligament (ACL) is an important stabilizer of the knee joint. After ACL rupture, the knee joint has difficulty maintaining its stability; thus the patient often has to receive an ACL-reconstructive surgery to regain the knee joint...

Title: MECHANICAL PROPERTIES OF ONE-DIMENSIONAL NANOSTRCTURES, EXPERIMENTAL MEASUREMENT AND NUMERICAL SIMULATION
Author: Wu, Xiaoxia
Date Created: 2012
Subjects--Topical: Mechanical engineering, Nanotechnology
Description: One-Dimensional (1D) nanostructures are generally defined as having at least one dimension between 1 and 100 nm. Investigations of their mechanical properties are important from both fundamental study and application point of view. Different metho...
