Kinematic analysis of cam profiles used in compound bows
(University of Missouri--Columbia, 2009)
for an eccentric-circular cam design and a one-cam one-pulley design. By iteratively determining the bow limb, cam, and cable positions a relationship between the drawn length and drawn force will produce a draw-force curve. In fact, this curve represents...
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 ...
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 ...
Analytical earth-aerocapture guidance
(University of Missouri--Columbia, 2020)
Aerocapture is a technique of employing a single atmospheric pass to inserts a spacecraft from a hyperbolic orbit, approaching from deep space, into an elliptical (captured) orbit around its destination planet. After ...
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 ...
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 ...
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 ...
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 ...
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...
3D polymeric scaffolds towards biomedical applications
(University of Missouri--Columbia, 2020)
, the assembly operation requires complicated actuation equipment and the assembled scaffolds are usually tethered on cumbersome elastomeric substrates. (3) For printing, few of scaffolds fabricated by emerging 4D printing technologies are responsive...
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
(University of Missouri--Columbia, 2010)
Much effort has been put into developing technologies for next generation re-usable launch vehicles. Fully re-usable launch vehicles include a booster stage that is designed to land, usually near the launch site, after it ...
Experimental investigation of liquid metal emulsion effect on the heat transfer performance of an oscillating heat pipe
(University of Missouri--Columbia, 2022)
This thesis introduces an oscillating heat pipe (OHP) charged with a hybrid fluid of gallium and ethanol. The hybrid fluid is fabricated using an ultrasonication technique to produce an emulsion-based mixture of liquid ...
