Sensitivity of Hashin damage parameters for notched composite panels in tension and out-of-plane bending

Creator:: Wright, Thomas J.
Abstract:: When using Finite Element Analysis (FEA) to model notched composite panels, the values of certain material properties can have a great effect on the outcome of the simulation. Progressive damage modeling is used to model how a composite structure will fail, and how that failure will affect the response of...

A theory of product design process measurement

Creator:: Wright, Alan Louis
Abstract:: This dissertation approaches the problem of how to design process measurements by identifying process attributes which are common to all product development processes. By classifying the generic attributes of a product development process and their relationships, a framework is established which gives definition and context to individual measurements. At the...

Exact frequencies and mode shapes of a rotating beam

Creator:: Wright, A. D. (Alan Duane), 1954-
Abstract:: The exact frequencies and mode shapes of flexural vibration of a rotating beam are found. The beam has a linear mass and stiffness distribution. With certain simplifying assumptions, the kinetic and potential energies of the rotating beam are found. Hamilton's principle is then used to determine the equation governing the...

Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

Investigation of Destratification in Warehouses

Creator:: Polander, Michael D.
Abstract:: A significant source of energy consumption comes from maintaining desired indoor environment conditions in warehouses and other industrial facilities. In efforts to combat the raising energy costs, studies into more efficient heating and cooling strategies has been a topic of consideration for a number of years. One of the areas...

Experimental investigation of natural convection from an array of uniformly heated horizontal cylinders to mercury

Creator:: Wang, Deing
Abstract:: An experimental investigation was conducted to better understand the heat transfer process with natural convection from an array of uniformly heated horizontal cylinders to mercury. Five assembly geometries were studied, these being the single horizontal cylinder, two cylinders with spacing ratios S/D = 2,3 and 4, (S represents the center-to-center...

Numerical and Experimental Evaluation of Membrane Based Energy Recovery Ventilator Performance with an Internal Support Structure

Creator:: Armatis, Paul D.
Abstract:: Large amounts of energy are wasted when conditioned air in buildings is exhausted to meet ventilation requirements. There are several technologies to recover some of this energy, including the recent development of membrane based energy recovery ventilators (ERVs). ERVs exchange sensible heat and moisture between incoming fresh and outgoing exhaust...

Analysis of a wood-fueled trimburner system for use in a combined-cycle, wood-fired power plant

Creator:: Stephenson, Jerry D.
Abstract:: This report investigates the use of wood to fuel a trimburner incorporated in a combined-cycle, biomass-fired power plant. The term "trimburner" applies to a ductburner which is designed to boost the temperature of the air stream entering the gas turbine. The work presented here is part of a larger biomass...
