Analytical And Experimental Methods For Determining The Properties Of Materials At Very High Rates Of Loading, A. G. Behring
Analytical And Experimental Methods For Determining The Properties Of Materials At Very High Rates Of Loading, A. G. Behring
Masters Theses
"In the following report, some of the properties of ALCOA 7075 T651 aluminum, when subjected to high rates of loading, are experimentally investigated by impacting two rods of the material longitudinally. One rod is accelerated to a uniform velocity with an air gun launcher. The stationary second rod is instrumented with strain gages on its lateral surface in order to determine the strain-time history following impact. A detailed description of the experimental equipment is included. Simple, one-dimensional theory is used to determine the dynamic, elastic modulus of the test material under the impact condition. Several observations regarding the behavior of …
An Unsteady-State Method For Determining The Thermal Conductivity Of Materials, Richard H. Bulmer
An Unsteady-State Method For Determining The Thermal Conductivity Of Materials, Richard H. Bulmer
Masters Theses
"Originally this work was initiated to develope [sic] a method for measuring the thermal diffusivity and thermal conductivity of metals. Due to the characteristics of the method and the equipment used, it was concluded that the technique is not suitable for materials of high conductivity. However, results show that the apparatus is valuable for the determination of the thermal diffusivity of relatively poor heat conductors. The favorable characteristics of the method are its rapidity and basic simplicity"--Abstract, page ii.

Vetters clay and Lebanon silt loam are used as test soils. these soils are ground to varying degrees and the deviations in physical properties are determined. Atterberg Limits, specific gravity, grain size, X-ray diffraction, and D.T.A. tests are run on each soil batch (ground for 0 minutes, 30 minutes, 60 minutes, and 120 minutes). A thixotropic study, consisting of unconfined compression and laboratory vane shear tests, of each soil batch is made. The results of the tests are analyzed, compared, and …
The Compressibility Of Preconsolidated Till, William H. Koechlein
The Compressibility Of Preconsolidated Till, William H. Koechlein
Masters Theses
"Preconsolidated glacial till was tested "in-situ" with the Geoprobe and in the laboratory on undisturbed soil samples. The two soil testing methods were compared and three tests; consolidation, "thin-cake", and Geoprobe were analyzed to see if a more rapid method for determining the preconsolidation stress of soil could be developed. When comparing Geoprobe results to laboratory results for foundation conditions, it was found the two methods agreed on bearing capacity but differed significantly on settlement. The three tests analyzed for determining the preconsolidation stress indicated they are a function of preconsolidation stress even though there was variation in the test …

A Study Of A Model-Referenced Adaptive Control System, James William Graham
A Study Of A Model-Referenced Adaptive Control System, James William Graham
Masters Theses
"A model-referenced adaptive controller for a first-order plant with time-varying parameters is developed using Lyapunov's second method. The system is studied with the aid of analogue computer simulation and an oscillatory mode is encountered. A method of reducing the oscillations by addition of a compensating network is proposed. The compensation is obtained through the use of linearization and root locus techniques. The compensated system shows a much improved error response over the original system"--Abstract, page ii.

Electronic Transitions In Diatomic Molecules, James O. Hornkohl
Electronic Transitions In Diatomic Molecules, James O. Hornkohl
Masters Theses
"The electronic transition moments of many band systems have been found to be linear functions of the internuclear distance. However, some band systems exhibit a quadratic variation of the transition moment. In these quadratic cases, the plots from which the variation of the transition moment is determined are based upon the approximation of the second r-centroid by the square of the first r-centroid. The square of the first r-centroid does closely approximate the second r-centroid by a simple error analysis shows that the small difference between the two is not a quantitative measure of the error introduced into the transition …

Effects Of Pressure On The Mechanical Properties Of Magnesium, Joseph George Hoeg
Masters Theses
"The data collected in an attempt to evaluate the pressure dependency of the mechanical properties of extruded AZ31B-F magnesium alloy are presented herein. This information was compiled from the results of compression tests run in hydraulic fluid environments pressurized to 50,000 psi, and tension tests run in the atmosphere. Specimen axial load and longitudinal strain were recorded and converted to effective stress and effective strain parameters for presentation. The term pressure is defined, in this report, as the negative average of the principal stresses or, essentially, the negative of the hydrostatic component of stress. The effective stress and strain, at …
Kinetics Of The Formation Of Strontium Zirconate, W. H. Parker
Kinetics Of The Formation Of Strontium Zirconate, W. H. Parker
Masters Theses
"The decomposition rate of strontium carbonate (SrC0₃) was measured using a TGA apparatus. It was found to deviate slightly from zero order classical reaction. The rate of formation of strontium zirconate (SrZr0₃) from zirconium oxide (ZrO₂) and strontium oxide (SrO) in the form of the decomposition product of SrCO₃ was measured using quantitative x-ray diffraction for mineralogical analysis. It was found to most nearly follow the Zhuravlev-Lesokhin-Tempel' man rate equation. The rate of decomposition of strontium carbonate was found to be more rapid than the rate of formation of strontium zirconate such that for the most part strontium oxide is …
Radiation And Annealing Characteristics In Neutron Bombarded Transistors Operated In The Inverse Configuration, Lo-Soun Su
Masters Theses
"When operating a silicon planar epitaxial transistor in the inverse configuration (i.e., with the emitter functioning as a collector and the collector functioning an emitter) the bulk space-charge volume of the new "emitter-base" junction is increased by a factor of 26.5 times that of the normal emitter-base junction. The carrier concentration in the new "emitter" is decreased by five orders of magnitude from that of the normal emitter, thus making it easier to investigate the effects of neutron radiation on the space-charge region and at the surface. Experiments using biasing of the new "emitter-base" junction during neutron radiation to change …
