Effects of constraint variation on the fatigue growth of surface flaws
(University of Missouri--Columbia, 1985)Studies have shown that fatigue growth of semielliptic surface flaws in plates is not adequately predicted solely by stress intensity factor analysis. The variation in stress field triaxiality along the flaw border must ... -
A holographic interferometry study of an axisymmetric shock-wave/boundary-layer strong interaction flow
(University of Missouri--Columbia, 1986)An experimental study of the axisymmetric shock-wave/ turbulent boundary-layer strong-interaction flow generated in the vicinity of a cylinder-cone intersection has been conducted. The present data are useful in the ... -
Stability and vibration characteristics of skew plates
(University of Missouri--Columbia, 1971)"Review of Literature. The deflection, stability, and vibration characteristics of rectangular plates have received considerable treatment in the literature. Solutions to the bending of rectangular plates with various ... -
Development of a multiple-specimen, reversed-flexure fatigue tester and its application to the testing of titanium sheet
(University of Missouri--Columbia, 1971)"Advancing technology constantly increases the demands on existing engineering materials. These demands are extremely severe for aerospace materials where the necessity for a higher strength-to-weight ratio is complicated ... -
An optical lateral control system for vehicles
(University of Missouri--Columbia, 1971)"It is evident that we will need a new mode of highway transportation within the next fifteen years. There are already 103 million vehicles (cars, trucks, and buses) on our roads; the majority of which are concentrated in ... -
Microstructural and environmental effects on fretting fatigue
(University of Missouri--Columbia, 1977)One of the primary causes of premature fatigue failures is a phenomenon known as fretting. The research leading to this paper consisted of developing information regarding microstructural and environmental effects on ... -
The extension of geometric programming to optimal mechanical design
(University of Missouri--Columbia, 1971)Geometric programming was developed in the early 1960’s by Clarence Zener, Richard J. Duffin, and Elmore L. Peterson as a method for minimizing a non-linear objective function subject to a set of non-linear inequalities. ... -
A study of the hardening mechanisms and microstructural characteristics of an improved dental amalgam
(University of Missouri--Columbia, 1975)Dispersalloy dental amalgam has been developed in the last twelve years and displays a significant decrease in creep rate and an increased resistance to corrosion. The manufacturer claims that the decreased creep rate ... -
Program for optimization of experimental data within a constrained configuration
(University of Missouri--Columbia, 1975)"The purpose of this thesis is to discuss and evaluate the development of a computer program for the optimization of a variable within a constrained situation. The objective of the program is to determine what combination ... -
An analysis of the induction time in the acetylene oxygen reaction
(University of Missouri--Columbia, 1971)"The importance of hydrocarbon combustion in flames and explosions of gases has long been recognized and hence continues to attract intensive investigation. Even though many new results are presented each year the proposed ... -
Investigation of the pressure-flow relationships of blood in the mammalian kidney
(University of Missouri--Columbia, 1970)This dissertation deals with the problem of quantification of the properties and activities of living tissue in the peripheral vasculature. The method of quantification is lumped hydraulic impedance analysis. The object ... -
A research tool for the chronic depulsation of the systemic circulatory system
(University of Missouri--Columbia, 1971)This research presents the development of a depulsation system for the chronic depulsation of the systemic circulations of a research animal. The system is designed so the animal may be alert and unrestrained while the ... -
Measurements and analyses of nasal and oral airflow during isolated sound productions by normal and cleft palate speakers
(University of Missouri--Columbia, 1971)Speech sound is produced through the superimposition of a coordinated series of progressive and dynamic processes. These processes include respiration, phonation, resonance, and articulation and are accomplished by making ... -
A study of parametric instability of eccentrically stiffened rectangular plates
(University of Missouri--Columbia, 1974)The purpose of the investigation was to determine the onset of parametric instability for a simply-supported rectangular stiffened plate subjected to periodic in-plane loads. The static buckling and the free vibration of ... -
Theory of flexure of orthotropic multi-layer circular sandwich plates
(University of Missouri--Columbia, 1968)The theory of flexure of multi-layer orthotropic circular sandwich plates is obtained by extremizing the augmented complementary energy. The complementary energy is the sum of the strain energies of the individual layers ... -
Force system synthesis to produce a desired time response of mechanisms
(University of Missouri--Columbia, 1975)A technique and computer programs are developed which will synthesize parameters of force systems which will drive a mechanism to have a desired motion-time response and desired input-output forces. The force devices can ... -
Local free convection to non-Newtonian fluids from a horizontal, isothermal cylinder
(University of Missouri--Columbia, 1972)The transfer of heat between a body surface and the motionless fluid surrounding it is perhaps one of the most naturally occurring physical phenomena. Undoubtedly interest and speculation regarding this natural or free ... -
Materials and structural innovations for bioelectronics and soft actuators
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 5/1/2024] Over the past few decades, technological advances have drastically altered people's lifestyles. One of the most relevant tech breakthroughs to everyday individuals is the commercialization of ... -
Validation of a micro-controller for oxygen control in the NICU
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 5/1/2024] Respiratory support is required for premature infants who are born with underdeveloped lungs and insufficient surfactant production, which is the cause of respiratory distress syndrome (RDS). The ... -
Pourous liquid metal-elastomer composites
(University of Missouri--Columbia, 2023)It is known that liquid metal-elastomer composites are promising soft conductors for skin-interfaced bioelectronics, soft robots, and other applications due to their large stretchability, ultrasoftness, high electrical ...
