Quantitative supersonic flow visualization by hydraulic analogy
(Texas A&M University, 1998)
The hydraulic analogy, which forms the basis for the phics. current investigation, can be used to study supersonic gas flows with great ease by means of a water table. As a result of the analogy, water heights in free ...
Using ultrasonic techniques to predict fracture toughness of AISI 4137 alloy steel
(Texas A&M University, 1997)
Previous studies have indicated the possibility of using ultrasonic attenuation as a nondestructive tool for predicting fracture toughness of metals. In all these studies, the fracture toughness was varied by changing the ...
Genetic algorithm based tomographic flow visualization
(Texas A&M University, 1997)
A new nonlinear tomographic flow visualization technique for use in limited data situations is developed using techniques from the emerging field of evolutionary computing. The new technique uses both pure and hybrid genetic ...
The bending and dynamic mechanical properties of cortical bone: the effects of sodium fluoride and the relationship to physical properties
(Texas A&M University, 1998)
Bone is a complex organic composite material. The graphics. interface between the mineral and organic phases of bone is significant both to medicine and to the biokinetics, a field which seeks to create advanced synthetic ...
Finite element analysis of a coiled composite tubular
(Texas A&M University, 1999)
This study presents the design and stress analysis of a composite tubular that can be coiled onto large spools for ease of storage and installation on offshore platforms. The tube is analyzed under working pressure and ...
Consolidation of aluminum 6061 powder by equal channel angular extrusion
(Texas A&M University, 1997)
Equal channel angular extrusion is a promising approach to obtaining full density in powder metallurgy applications. This method can impose large effective deformations through uniform shear strain. Aluminum alloy 6061 ...
Effect of unsteady wake passing frequency on boundary layer transition on the concave surface of a curved plate
(Texas A&M University, 1997)
The unsteady boundary layer behavior on the concave surface of a curved plate is investigated. Detailed experimental investigations are carried out to study the effect of unsteady wakes on the boundary layer transition ...
The development of an experimental procedure to determine the amount of active internal friction in a rotor-bearing system
(Texas A&M University, 1997)
This research presents a method to determine the active friction force in a free-free rotor. This method is based on Gunter's work in SP-1 13 and assumes that the active internal friction force is a function of bending ...
Numerical and experimental study on the effects of elbows upon the flow downstream
(Texas A&M University, 1998)
The seeds of elbows upon the flow downstream were graphics. studied experimentally and numerically. The flow field was calculated for five cases: through one elbow, through two elbows arranged to make an S bend in a single ...
Determining the effect of seawater on the interfacial shear strength of fiber reinforced epoxies using the single fiber fragmentation test
(Texas A&M University, 1996)
Potential uses for fiber reinforced polymer composite materials in the petroleum industry, especially in offshore applications, is substantial. Most fiber reinforced polymer composites currently used in offshore are found ...
