(2014-12-12)Metallic nuclear fuels, as potential candidates in advanced reactors development, have been extensively studied for over five decades. The main challenges are the fuel performance designed for higher burn-up and higher ...
-
(2021-07-26)The overarching goal of this dissertation is to quantify the microstructural influence on deformation, degradation, and fracture of some of the most technologically sought after advanced structural materials. In the first ...
-
(2017-12-04)The presence of hydrogen in structural metals and alloys especially steels has proven to be a problem warranting a significant amount of attention for over a century. In steels presence of hydrogen severely degrades its ...
-
(2021-04-28)Single crystal superalloys, mostly Nickel-based, have been, so far, the material of choice for high-temperature applications, such as gas turbine blades. Single crystalline turbine blades are usually cast in the direction, ...
-
(2021-09-13)Technological advancements such as efficient jet engines and nuclear reactors rests on our ability to design and discover new materials. Historically, discovery of new materials has relied on Edisonian approach, but it is ...
-
(2020-07-01)Ductile fracture involving nucleation, growth and coalescence of microscale voids limits the manufacturability and mechanical performance of a variety of structural materials. This phenomenon is affected by length-scales ...
-
(Texas A&M University, 2005-11-01)Triaxial extension experiments on Carrara Marble demonstrate that there is a continuous transition from extension to shear fracture on the basis of mechanical behavior, macroscopic fracture orientation and fracture morphology ...
-
(Texas A&M University, 2004-09-30)This dissertation presents the development of an anisotropic viscoplastic continuum damage model to describe the permanent deformation of asphalt pavements. The model is developed to account for several phenomena that ...

(2017-05-05)Vertically aligned nanocomposite (VAN) presents as a novel material platform for creating high-quality self-assembled, nano-pillars of one phase in matrix of another structures. In the past decade, extensive efforts have ...
-
(Texas A&M University. Libraries, 1999)The objectives of this research were to process commercial Al - 5083 using equal channel angular extrusion routes A, B, and C, include intermediate solution-heat treatments, investigate the room temperature and superplastic ...
-
(2020-07-22)Asphalt is one of the most commonly used materials in the road construction industry. Asphalt binder is used to bind aggregate particles to form the asphalt mixture, which is the material used for the construction of ...
-
(2009-05-15)Copper has become the metal of choice for metallization, owing to its high electrical and thermal conductivity, relatively higher melting temperature and correspondingly lower rate of diffusivity. Most of the current studies ...
-
(Texas A&M University, 1993)Residual stress and microstructure evaluation of ductile cast iron using a nondestructive method (Critically Refracted Longitudinal Ultrasonic Wave Technique) was approached. Residual stresses, both good and bad graphite ...
