Guduk, Bulent (2022-07-27)In this study, computational fluid dynamics (CFD) simulations were performed using the Fluent and Mechanic module of ANSYS application to characterize the aerodynamic and static behavior of a horizontal axis wind turbine ...
-
Bauer, Peter Hamill (2022-04-06)The focus of this research is on the friction interactions between railroad crossties and ballast material. These friction interactions change over time as the crossties experience continued loading due to passing trains. ...
-
Dorsett, Garrett (2023-05-02)Aerial transportation infrastructure is vital to connecting communities across the United States and the globe. It provides critical support functions in transporting purchased goods and resources, providing access to ...
-
Musu, Valentina (2023-07-09)A model is developed herein for predicting the onset of environmentally induced buckling in rail structures. As described below, the model may be considered to be an extension of previous efforts spanning much of the ...
-
Erener, Osman (2021-12-07)This study is part of a larger research effort to investigate the mechanical response of composite beams to cyclic loading caused by waves striking beams imbedded in a low-cost sea wall. In the course of the research, it ...
-
Toerner, Hannah Elizabeth (2020-04-13)This research focuses on the analysis of the mechanical responses of a recycled high-density polyethylene glass fiber composite material when subjected to uniaxial tension fatigue. The desired properties were determined ...

LONG-TERM BEHAVIOR OF BALLAST IN RAILWAY EMBANKMENT UNDER HIGH-SPEED TRAIN AND FREIGHT TRAIN LOADING Mahdavi Kharanaghi, Mohammad (2020-07-28)The behavior of the railway ballast under the operation of high-speed trains and heavy freight trains is studied in this dissertation. For this purpose, a combination of laboratory testing and numerical simulations has ...
-
Harmouche, Mahmoud Redwan (Texas A&M University. Libraries, 1988)This dissertation deals with the subject of testing the methodology of the PUCOT (Piezoelectric Ultrasonic Composite Oscillator Technique) for measuring the elastic constants, providing an improved method of using sound ...

Xue, Lufeng (2022-11-28)A new high entropy alloy (HEA) system, Al2Cr5Cu5Fe53Ni35 is designed, synthesized and characterized. In order to improve its properties, several grain refinement treatments including cold rolling and annealing are conducted. ...
-
Cammarata, Juliana E (2015-12-12)The objective of this study is to determine whether exposing an asphaltic roadway to standing liquid water for a duration of twelve hours will cause sufficient moisture penetration to induce deterioration of the roadway. ...
-
Trevino, Alexis (2018-05-08)The proposed work involves developing a wind turbine system that charges batteries to provide required power of sensing and communication systems, while railroad operates at expected operating conditions. For this project, ...
