A parabolic quadrilateral finite element for compressible and incompressible flows
(Massachusetts Institute of Technology, 1998)
A unified finite element solution scheme for incompressible and compressible flows would be most attractive in engineering practice. The objective in this thesis was to work toward this goal. A 9-node finite element for ...
Synthesis and analysis of a microcellular plastics extrusion system for insulation of fine wires
(Massachusetts Institute of Technology, 1998)
This thesis deals with analytical and experimental work performed on the extrusion of microcellular plastics with cell sizes of 20 microns or less and cell densities of about a billion cells per cm3. An analytical model ...
Crashworthiness analysis of ultralight metal structures
(Massachusetts Institute of Technology, 1999)
In the design of light weight crashworthy metal structures, thin-walled prismatic components have been widely used in aircraft, high speed trains, fast ships, and automobiles. Two new types of such components are proposed, ...
Towards optimal mixed finite elements for general shell structures
(Massachusetts Institute of Technology, 1999)
Optimal finite elements are available for many engineering applications, such as incompressible media, beam and plate bending problems. However, no existing general shell elements have been shown to satisfy the mathematical ...
The influence of alloy composition and interfacial segregants on the fracture and fatigue of metal/ceramic interfaces
(Massachusetts Institute of Technology, 1999)
The use of multi-layered composites in the aircraft, automotive, and electronics industries is becoming more common as performance requirements exceed the capabilities of homogeneous materials. As a result, the need to ...
On the dynamics of draw texturing.
(Massachusetts Institute of Technology, 1976)
Rural electrification from local resources : biomass pyrolysis oil combustion in a direct injection diesel engine
(Massachusetts Institute of Technology, 1998)
As the production process continues to be refined, biomass pyrolysis oils are increasingly being considered as potentially feasible renewable fuels. Combustion of pyrolysis oils in diesel engines has been scarcely studied, ...
Cell-matrix interactions : collagen-GAG scaffold fabrication, characterization, and measurement of cell migratory and contractile behavior via confocal microscopy
(Massachusetts Institute of Technology, 2006)
Three-dimensional, collagen scaffolds are an analog of the extracellular matrix and are used for many tissue engineering applications. While material and microstructural properties significantly affect overall scaffold ...
Design of a thermal control system for an IC test-in-tray handler
(Massachusetts Institute of Technology, 1998)
This work reports the design of a fundamentally new semiconductor integrated circuit (IC) test handler thermal system, and its implementation in the development of a new commercially-sold product. The test handler is a ...
A study of a supersonic axial flow compressor
(Massachusetts Institute of Technology, 1949)
