da Silva Soares, Joao Filipe (Texas A&M University, 2008-10-10)Percutaneous transluminal balloon angioplasty followed by drug-eluting stent implantation has been of great benefit in coronary applications, whereas in peripheral applications, success rates remain low. Analysis of healing ...
-
Prasad, Sharat Chand (Texas A&M University, 2006-10-30)In this work, a constitutive theory is developed, within the context of continuum mechanics, to describe the creep deformation of single crystal superalloys. The con- stitutive model that is developed here is based on the ...
-
Shah, Sneha (2010-01-16)This study analyzes the thermo-mechanical response of a composite cylinder made up of two layers of linear isotropic viscoelastic materials that belong to the class of non-Thermorheologically Simple Material. The effect ...
-
Dhar, Sandeep (2011-10-21)In this dissertation, we focus on development of algorithms for estimating the severity of air leakage and for predicting the out-of-adjustment of pushrod in an air brake system of heavy commercial vehicles. The leakage ...
-
Song, Min Jae (2009-05-15)It has been proven by J.C.Criscione that constitutive relations(mixed approach) based on a set of five strain invariants (Beta-1, Beta-2, Beta-3, Beta-4, Beta-5) are useful and stable for experimentally determining response ...
-
Ravishankar, Arun (2012-07-16)This thesis employs a finite element (FE) method for numerically simulating the mechanical response of constituents in a fiber-reinforced polymer (FRP) composite to indentation. Indentation refers to a procedure that ...

Mohan, Anand (Texas A&M University, 2006-10-30)Multiple interacting mechanisms control the formation and dissolution of clots to maintain blood in a state of delicate balance. In addition to a myriad of biochemical reactions, rheological factors also play a crucial ...
-
Vilayannur Natarajan, Shankar (Texas A&M University, 2005-08-29)Statistics indicate that defects in brake system contribute significantly to fatal crashes involving commercial vehicles. Hence there is a need for developing preventive and active safety measures for assessing the performance ...
-
Bowlin, Christopher Leland (Texas A&M University, 2007-04-25)This research is focused on developing a control scheme for regulating the pressure in the brake chamber of an air brake system found in most commercial vehicles like trucks, tractor-trailers and buses. Such a control ...

Le Roux, Christiaan; Rajagopal, Kumbakonam R. (Applications of Mathematics, 2013)
-
Ravindran, Parag (2009-06-02)Asphalt bound mixtures have been put to diverse uses. The complicated nature of the material and the demanding conditions under which it is used preclude complete solutions to questions on load bearing capability under ...

Studying Problems in Elasticity and Plasticity Using a QR Decomposition of the Deformation Gradient Paul, Sandipan (2021-05-25)With the recent developments of QR kinematics and the associated constitutive model, in this thesis, we address some of the fundamental issues in QR kinematics and extend this method to study some problems in elasto-plasticity. ...
-
Karra, Satish (2012-07-16)Materials like asphalt, asphalt concrete and polyimides that are used in the transportation and aerospace industry show viscoelastic behavior. These materials in the working environment are subject to degradation due to ...
