Oxidation resistant carbon-carbon composites: the effect of temperature dependent matrix material properties on laminate response
(Texas A&M University, 1994)
The structural analysis of carbon-carbon (C-C) composites is a research area of increasing importance. As the use of the materials expands towards more demanding aerospace applications, it is of critical importance to ...
The characterization of Lamb and Rayleigh waves in plates with ramp-like changes in thickness
(Texas A&M University, 1994)
The research described in this thesis uses broadband laser generation and detection techniques to investigate acoustic wave propagation in wedge type structures. The interrogating waves were generated by a Q-switched ND:YAG ...
The effect of drying on the heating value of biomass fuels
(Texas A&M University, 1994)
There has been some speculation as to whether or not biomass fuels (such as feedlot manure) may lose volatile matter during the drying process. Since current standards state that heating value analysis may be performed ...
Stiffness reduction and stress transfer in composite laminates with transverse matrix cracks
(Texas A&M University, 1994)
Cross-ply laminates and angle-ply laminates with transverse plies containing through-width matrix cracks across the thickness of the transverse plies are studied using a variational, strain energy based approach, complementary ...
Automating DNA processing
(Texas A&M University, 1994)
Technology is currently available to identify the genetic codes responsible for physical traits and genetic diseases in both plants and animals. Regardless of whether the final goal is medical diagnosis or breeder selection, ...
Dynamic pressure and shear stress measurements on the stator wall of whirling annular seals
(Texas A&M University, 1994)
Dynamic pressure and shear stress measurements on the stator wall of whirling annular seals are presented. Two flow conditions (Re=12,000 & 24,000), two seal speeds (Ta=3,300 & 6,600) and three eccentricity ratios (0, 10, ...
Determination of the fracture parameters associated with mixed mode displacement fields and applications of high density geometric moire
(Texas A&M University, 1994)
There were two objectives in this research: to develop a high density film grating (80 lines/mm) suitable for use in geometric moire experiments and to develop an algorithm which could be used to determine the fracture ...
Development of analytical and numerical models predicting the deposition rate of electrically charged particles in turbulent channel flows
(Texas A&M University, 1994)
An analytical model is established to predict an electrostatically charged particle deposition as a function of particle size in fully-developed turbulent pipe flow. The convectivediffusion flux equation is solved for the ...
Grading of lumber using stress waves
(Texas A&M University, 1994)
The goal of this research was to develop stress wave grading technology suitable for small lumber mills. Specific goals include: 1) develop an ultrasonic probe configuration to facilitate real-time grain angle and edge ...
Development of slotted orifice flow conditioner
(Texas A&M University, 1994)
Flow condit ioners are used extensively in orifice metering facilities upstream of the orifice in an attempt to produce fully developed turbulent pipe flow without the necessity of long upstream pipe lengths. Tube bundles ...
