(2022-08-23)Spatial BiGlobal (SBG) theory was used to study boundary-layer transition on a hypersonic finned cone. A new solver, BLAST, has been developed to apply the equations in a nonorthogonal manner, which extends its applicability ...
-
(2015-08-13)This dissertation addresses research problems related to the switched system as well as its application to large-scale asynchronous dynamical systems. For decades, this switched system has been widely studied in depth, ...
-
(2009-05-15)Textile composites have a wide variety of applications in the aerospace, sports, automobile, marine and medical industries. Due to the availability of a variety of textile architectures and numerous parameters associated ...
-
(Texas A&M University, 2005-11-01)Shape Memory Alloys (SMA) are a group of metallic alloys that have the ability to return to some previously defined shape or size when subjected to an appropriate thermal cycling procedure. In recent years there has been ...
-
(Texas A&M University, 2006-04-12)Rapid Distortion Theory is used to perform calculations of unsteadily-forced initially isotropic turbulence so that the physics of such flows can be better understood. The results of these calculations show that there are ...
-
(2011-05-20)Spacecraft design is inherently difficult due to the nonlinearity of the systems involved as well as the expense of testing hardware in a realistic environment. The number and cost of flight tests can be reduced by ...
-
(2021-04-13)Solving nonlinear optimal control problems can be a difficult and time intensive process. This is especially true when the state dynamics of the problem are computationally expensive to solve. Using the Theory of Functional ...
-
(Texas A&M University, 2005-11-01)In this dissertation, we present the Slattery-Oh-Fu theory extending continuum mechanics to the nanoscale and its applications. We begin with an analysis of supercritical adsorption of argon, krypton, and methane on Graphon ...
-
(2020-08-05)Preliminary design is a complicated problem that is often solved using topology optimization. In this work, a heuristic approach to topology optimization is considered. This approach involves the coupling of a genetic ...
-
(Texas A&M University, 2006-10-30)The thermodynamics of three-dimensional, single-component elastic crystalline solids was developed by Slattery and Lagoudas (2005). Considering the inïnitesimal deformations, the stress can be expressed as a function ...
-
(Texas A&M University, 2006-10-30)The thermodynamic behaviors of multicomponent, elastic, crystalline solids under stress and electro-magnetic fields are developed, including the extension of EulerâÂÂs equation, Gibbs equation, Gibbs-Duhem equation, the ...
-
(2016-08-25)This dissertation explores new approaches for modeling perturbed and unperturbed satellite relative motion. It extends Hoots orbit theory, an analytical averaging-method perturbation solution to the Zonal Problem, to ...
-
(2014-08-04)The objective of this investigation is to develop a single point model for the global effects of pressure in turbulence, while striking a judicious balance between mathematical rigor and empiricism. In this vein, we perform ...
-
(2013-12-02)Wind tunnels are designed for a certain range of test velocities and model sizes. The Oran W. Nicks Low Speed Wind Tunnel (LSWT) at Texas A&M, was designed to reach 200 mph (M=0.26) with its original 1250 hp motor and 7 x ...
-
(2011-02-22)The research presented in this dissertation pertains to the evaluation of stiffness of carbon nanotubes (CNTs) in a multiscale framework and modeling of the interfacial mechanical behavior in CNT-polymer nanocomposites. ...
-
(2010-01-14)Automated spacecraft docking is a concept of operations with several important potential applications. One application that has received a great deal of attention recently is that of an automated docking capable unmanned ...
-
(2020-05-19)Autonomous navigation capabilities for spacecraft are useful for decreasing operational costs, increasing the scope of missions, and increasing the robustness of spacecraft. This dissertation aims to present and fully ...
-
(2011-08-08)Current orbital solutions for 99942 Apophis predict a close approach to the Earth in April 2029. The parameters of that approach affect the future trajectory of Apophis, potentially leading to an impact in 2036, 2056, 2068, ...
-
(Texas A&M University, 2007-04-25)The finite element method since its development in the 1950âÂÂs has been used extensively in solving complex problems involving partial differential equations. The conventional finite element methods use piecewise ...
