(2018-08-27)Fused Deposition Modeling (FDM) is an extrusion based additive manufacturing methodology. During the manufacturing process, a thread of thermoplastic material is melted through the extruder and solidified on the building ...
-
(Texas A&M University, 2006-04-12)The focus of the research is to develop a consistent and repeatable method to evaluate the coefficient of thermal expansion (CTE) of carbon fibers at high temperatures. Accurate measurement of the CTE of carbon fibers ...
-
(2021-04-06)A model is developed herein for predicting the onset of thermally induced buckling in the horizontal and vertical planes for rail structures. As described below, the model may be considered to be an extension of previous ...
-
(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 ...
-
(2020-03-12)Formation sand production has been a recurring problem for the oil and gas industry since the advent of the hydrocarbon exploration and extraction. The effects of sand production are adverse in nature and are two folds; ...
-
(2010-10-12)As part of a larger effort to understand the fundamental knowledge of polymer scratch behavior, this dissertation is focused on both experimental study and numerical analysis of scratch deformation of a broad range of ...
-
(2019-09-03)The surface finite element method is an important tool for discretizing and solving elliptic partial differential equations on surfaces. Recently the surface finite element method has been used for computing approximate ...
-
(2021-04-29)Astronauts undergo significant bone loss during spaceflight. The lack of gravitational loading increases bone resorption and decreases bone formation in weightbearing bones, resulting in a net loss of bone. NASA traditionally ...
-
(2017-04-18)Upper bound plastic limit analysis (PLA) solutions have been widely used to assess maximum capacity of laterally loaded piles and caissons. However, for the specific case of short piles and caissons with aspect ratios ...
-
(2017-07-28)We study multiphase, multicomponent flow of incompressible fluids through porous media. Such flows are of vital interest in various applied science and engineering disciplines like geomechanics, groundwater flow and ...
-
(2011-02-22)Overhead transmission lines are periodically inspected using both on-ground and helicopter-aided visual inspection. Factors including sun glare, cloud cover, close proximity to power lines and the rapidly changing visual ...
-
(2018-05-22)The negative powers of an elliptic operator can be approximated via its Dunford-Taylor integral representation, i.e. we approximate the Dunford-Taylor integral with an exponential convergent sinc quadrature scheme and ...
-
(2013-07-16)Better understanding and control of crack growth direction during hydraulic fracturing are essential for enhancing productivity of geothermal and petroleum reservoirs. Structural analysis of fracture propagation and impact ...
-
(Texas A&M University, 2004-09-30)Spontaneous imbibition plays a very important role in the displacement mechanism of non-wetting fluid in naturally fractured reservoirs. We developed a new 2D two-phase finite element numerical model, as available commercial ...
-
(2011-08-08)The multi-scale modeling of ion-solid interactions presented can lead to a fundamentally new approach for understanding temperature evolution and damage formation. A coupling of the Monte Carlo code, SRIM, to a C FEM ...
-
(2013-08-09)The thesis considers three-dimensional analyses of fractures and wellbores in low-permeability petroleum/geothermal reservoirs, with a special emphasis on the role of coupled thermo-hydro-mechanical processes. Thermoporoelastic ...
-
(2009-05-15)In this thesis, mixed finite element models of beams and plates bending are developed to include other variables (i.e., the membrane forces and shear forces) in addition to the bending moments and vertical deflection, and ...
-
(2018-04-27)This research presents a method to measure and calculate residual stress in A36 steel after submerged arc welding. Finite element is used to simulate the welding process and is compared with experimental data. After ...
