Numerical Simulation Of Thermo-Elasticity, Inelasticity And Rupture Inmembrane Theory, Michael Taylor
Numerical Simulation Of Thermo-Elasticity, Inelasticity And Rupture Inmembrane Theory, Michael Taylor
Mechanical Engineering
Two distinct two-dimensional theories for the modeling of thin elastic bodies are developed. These are demonstrated through numerical simulation of various types of membrane deformation. The work includes a continuum thermomechanics-based theory for wrinkled thin films. The theory takes into account single-layer sheets as well as composite membranes made of multiple lamina. The resulting model is applied to the study of entropic elastic elastomers as well as Mylar/aluminum composite films. The latter has direct application in the area of solar sails. Several equilibrium deformations are illustrated numerically by applying the theory of dynamic relaxation to a finite difference discretization based …

Nanoengineered Templates For Controlled Delivery Of Bioactive Compounds, Nalinkanth Ghone Veerabadran
Doctoral Dissertations
The significance of any drugs, therapeutic proteins, or any bioactive compounds, is based not only on their effects on diseases but also on how specifically, how readily, how controllable and how prolonged their effects on the disease without having any side effects. Thus the techniques involved in the drug encapsulation and its controlled release for a longer duration of time form one of the important processes of drug reformulation. In recent years nanoparticles have created overwhelming attention for delivering drugs by nanoencapsulation. The smaller size of nanoparticles has longer circulation time and higher cellular uptake when compared with larger size …
Planning And Adaptation Measures For Urban Slum Communities In West Africa : Stochastic Rainfall Modeling Applied To Domestic Rainwater Harvesting And Climate Change Adaptation, Joshua R. Cowden
Dissertations, Master's Theses and Master's Reports - Open
Over half of the world’s population is living in urban settlements, and most urban growth is occurring in developing countries. These countries’ economies are often unable to accommodate these rural-urban immigrations, resulting in millions of people settling in insecure communities known as urban slums. Current efforts to prevent urban slums include UN-HABITAT strategies to upgrade slums and stimulate urban/regional development. Urban metabolism analysis, which studies material and energy flows/stocks through urban processes, help decision-makers better understand their urban system. Nine lessons from past urban metabolism studies are presented to assist in finding answers on how to best solve urban slum …

Unsteady Incompressible Navier-Stokes Simulations On Deforming Domains, Atefeh Shadpour
Electronic Theses and Dissertations
Mesh generation has been an important topic of research for the past four decades, primarily because it is one of the critical elements in the numerical simulation of fluid flows. One of the main current issues in this regard is mesh generation and flow solution on domains with moving boundaries. In this research, a novel scheme has been proposed for mesh generation on domains with moving boundaries, with the location of boundary nodes known at any particular time. A new set of linearized equations is derived based on a full nonlinear elliptic grid generation system. The basic assumption in deriving …
