(2023-05-05)For many physical problems, robust numerical methods for solving the compressible Euler equations are essential. For the Euler equations to accurately describe the fluid behavior a suitable equation of state (EOS), which ...
-
(1984)Deflection is often the dominant design criterion of a flexural member. The theoretical methods commonly used to determine beam deflections become extremely complex for irregular and combined loading conditions. A finite ...
-
(2017-01-17)Finite element procedures combined with microstructure development modeling are integrated to quantitatively predict the viscoelastic/viscoplastic relaxation of cement paste due to intrinsic calcium silicate hydrate ...
-
(2010-07-14)Abdominal aortic aneurysms (AAA) are an expansion in diameter of the abdominal aorta and their rupture is a leading cause of mortality. One of the treatments for AAA is the implantation of an endograft (also called a stent ...
-
(2019-03-26)Machinery trains with motor drives are widely used in industry. Motor related forces may become one of the sources of machinery vibrations. Motor eccentricity is one of the common phenomena that cause forces exerted on ...
-
(Texas A&M University, 2005-11-01)The solution of the secondary coupled-vector potential formulation of Maxwell??s equations governing the controlled-source electromagnetic (CSEM) response of an arbitrary, threedimensionalconductivitymodelmust be ...
-
(2016-12-09)Many engineering and scientific applications deal with models that have multiple spatial scales, and these scales can be non-separable. Many of these processes can exhibit nonlinearities and have a tight coupling with the ...
-
(Texas A&M University, 2004-09-30)We consider the application of least-squares variational principles and the finite element method to the numerical solution of boundary value problems arising in the fields of solidand fluidmechanics.For manyof these ...
-
(2011-02-22)Electric field guided assembly of colloids is a new area of research in colloidal science where sub-micrometer particles, or colloids, are assembled using patterned electrodes. The design of these devices is often limited ...
-
(2011-02-22)This dissertation addresses new developments in the constitutive modeling and structural analysis pertaining to rate-independent and rate-dependent irrecoverable inelasticity in Shape Memory Alloys (SMAs). A new model for ...
-
(2020-11-05)A nonlinear three-dimensional finite element numerical code, called RISER3D, has been developed to perform the static, eigenvalue, and dynamic analyses for slender structures such as beams and marine risers. Distinction ...
-
(2015-07-09)This thesis is devoted to theoretical and experimental justifications of numerical methods for fractional differential equations, which have received significant attention over the past decades due to their extraordinary ...
-
(2012-11-12)Down-hole damages such as borehole collapse, circulation loss and rock tensile/compressive cracking in the open-hole system are well understood at drilling and well completion stages. However, less effort has been made to ...
-
(Texas A&M University, 2008-10-10)In this dissertation we discuss the development, implementation, analysis and testing of the Piecewise Linear Discontinuous Finite Element Method (PWLD) applied to the particle transport equation in two-dimensional ...
-
(2013-12-02)Scratch-induced surface deformation is a complex mechanical process due to high strain rate large-scale deformation, non-linear material response, heat dissipation and complex stress field evolved during the process. The ...
-
(2011-08-08)Vascular stents have become a standard for treating atherosclerosis due to distinct advantages in trauma and cost with other surgical techniques. Unfortunately, the therapy is hindered by the risk of a new blockage (termed ...
-
(Texas A&M University, 2005-02-17)Elliptic partial differential equations that are used to model physical phenomena give rise to large sparse linear systems. Such systems can be symmetric positive definite and can be solved by the preconditioned conjugate ...
