Investigation of static interfacial fracture in orthotropic-orthotropic composite bimaterials using photoelasticity
(University of Missouri--Columbia, 2009)
The effects of static Mode I (opening mode) and mixed-mode (both Mode I - opening mode and Mode II - shear mode present) loading on orthotropic-orthotropic bimaterial interface cracks and isotropic-orthotropic bimaterial ...
Galilean moon tour using simplified trajectory computational techniques
(University of Missouri--Columbia, 2006)
It is desired to find a trajectory for a spacecraft that will capture into an orbit about Jupiter and then subsequently capture into an orbit about each of the Galilean moons. The two main variables are the mass ratio, ...
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 ...
Analysis and modeling of direct selective laser sintering of two-component metal powders
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Direct Selective Laser Sintering (SLS) is an emerging technology of Solid Freeform Fabrication (SFF) that 3-D parts are built from the metal-based ...
Semi-analytical terminal and automatic approach and landing trajectory planners for unpowered reusable launch vehicle
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A new guidance scheme for the terminal area energy management (TAEM) phase of an unpowered reusable launch vehicle (RLV) has been developed. The main ...
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 ...
System modeling and control design of a two-stage metering poppet-valve system
(University of Missouri--Columbia, 2006)
control methods that comprise modified PI control, LQG control, H [mobius] control, and nonlinear feedback control are used to make a closed-loop poppet system. The nonlinear controller is only applied to the nonlinear system and certified by Lyapunov...
Design and analysis of origami-inspired structures
(University of Missouri--Columbia, 2022)
This work focuses on creating novel structures by combining elements of common origami patterns. Multiple different types of physical and computer models are implemented to represent and analyze the structures. These ...
Numerical and experimental investigations on capillary-driven thin-film evaporation with applications in pumped two-phase loop and loop thermosyphon
(University of Missouri--Columbia, 2020)
and tubular wick posts. The evaporation mode transition from flooded to thin-film evaporation was detected by the evaporator thermal resistance which is directly related with the liquid level in the monolayer wick base. In Chapter 4, an active flow control...
Sensitivity analysis and optimal design of conventional and magnnetorheological fluid brakes
(University of Missouri--Columbia, 2018)
Mechanical and electrical brakes have dominated the braking industry for many years and will most likely continue to do so for the foreseeable future due to their low cost and adequate operating performance, wide range of ...
Nonlinear mechanics and testing of highly flexible one-dimensional structures using a camera-based motion analysis system
(University of Missouri--Columbia, 2006)
Both experimental and theoretical investigations are conducted for the dynamics of cables and strings. The exact equations of motion for finite but small amplitude vibration of string were derived based on a fully nonlinear ...
Automated trajectory generation and guidance for a new launch vehicle flight phases
