(2019-07-29)Since the addition of Hf or Zr provides a cost-effective alternative to NiTi alloyed with Pd, Pt and Au, due to the high cost of the latter, NiTiHf and NiTiZr alloys have recently attracted considerable attention [1]. In ...
-
(2009-05-15)In order to keep up with the world’s energy demands, oil and gas producing companies have taken the initiative to explore offshore reserves or drill deeper into previously existing wells. The consequence of this, however, ...
-
(Texas A&M University. Libraries, 1983)A new approach to the characterization of pavement mixtures' toughness based on the J integral concept was developed. The fracture mechanics approach was used to compare fatigue and fracture characteristics of new plasticized ...
-
(Texas A&M University, 2006-08-16)Hot-mix asphalt concrete (HMAC) mixture fatigue characterization constitutes a fundamental component of HMAC pavement structural design and analysis to ensure adequate field fatigue performance. HMAC is a heterogeneous ...
-
(Texas A&M University. Libraries, 1986)This dissertation begins with a review of the bases for creep constitutive equations. Next, physical metallurgical concepts are used to examine the creep process in simple and complex stress histories. Since, there are ...
-
(Texas A&M University. Libraries, 1977)Cylindrical specimens of 7075-T6 aluminum alloy were subjected to reversed shear stress and static mean stress to study the effect of mean static tensile stress on cumulative fatigue damage under reversed shear stress. The ...
-
(2017-05-09)Fatigue of steel is a major cause of mechanical failure and as such is very important to the safe design of railroad bridges. Fatigue phenomena are governed by the creation and growth of cracks, which can propagate through ...
-
(2008-08-19)The primary objective of the present investigation is to study the fatigue characteristics of a woven carbon fiber reinforced polymer which has been modified with either amine or fluorine functionalized carbon nanotubes ...
-
(2013-11-08)This dissertation has two key objectives: the first objective is to develop a method of predicting and quantifying the amount of water that can enter into a pavement system by vapor transport; the second objective is to ...
-
(2012-07-16)The railroad industry plays a pivotal role in commerce and greatly impacts America's economy. With this in mind, they cannot afford downtime or service interruptions due to bridge or member replacement. Corrosion of bridges ...
-
(2023-08-03)Fatigue in the workplace is a growing concern in industries and is seen as a work hazard that can impair workers’ physical and cognitive abilities. This leads to an increased number of incidents, injuries, and fatalities, ...
-
(2013-12-06)Chances of cement sheath failure increase considerably when the application involves deep, high pressure/ high temperature (HPHT) wells. Such failures occur as a result of temperature and pressure-induced stresses created ...
-
(2018-12-11)Anxiety disorders are the most commonly diagnosed psychological disorders in the United States. They are often comorbid with other psychological disorders, most commonly depressive disorders. Anxiety and depression are ...
-
(2018-08-02)The degradation of metallic systems under cyclic loading is prone to significant uncertainty. This uncertainty in turn affects the reliability in the prediction of residual lifetime and the subsequent decision regarding ...
-
(2012-07-16)The Constitution Truss Spar, operated by Anadarko Petroleum Corporation (APC), is located in Green Canyon Block 679 and 680 in a water depth of 1,500 m. It was installed in October of 2006 and has since weathered multiple ...
-
(2019-11-25)Offshore conductors are an integral part of the oil and gas well and they support the motions from the riser, which are usually subjected to environmental loads. These structures are designed to meet requirements for ...
-
(2011-02-22)The fatigue life of a Steel Catenary Riser (SCR) near its touch-down zone is substantially affected by its interaction with the seabed. Hence, accurate estimate of its fatigue life requires the understanding and realistic ...
-
(Texas A&M University. Libraries, 1986)Concepts of elastic fracture mechanics are applied to an airfield pavement material. The material used to conduct the experimental work is a portland cement stabilized fine grained soil. Two primary areas of interest and ...
-
(2009-05-15)Fatigue cracking is one of the primary modes of distress in asphalt pavements that has an important economic impact. Fatigue resistance characterization of an asphalt mixture is a complex issue due to: (i) composite ...
