Strain-Based Mechanical Failure Analysis Of Buried Steel Pipeline Subjected To Landslide Displacement Using Finite Element Method, Sean Goodluck Mamuzo Edeki
Strain-Based Mechanical Failure Analysis Of Buried Steel Pipeline Subjected To Landslide Displacement Using Finite Element Method, Sean Goodluck Mamuzo Edeki
Electronic Theses and Dissertations
Landslide displacement is one of the major threats to the structural integrity of buried oil and natural gas pipelines that are often located far from major markets with terrains prone to permanent ground deformations. These pipelines can experience large longitudinal strains and circumferential deformation resulting from the differential ground movements thereby potentially impacting pipeline safety by adversely affecting structural capacity and leak tight integrity. In order to proffer theoretical basis for the design, safety evaluation and maintenance of pipelines, the failure analysis and mechanical behavior of buried API X65 steel pipeline perpendicularly crossing landslide area was investigated with the Finite …
Effect Of Poisson’S Ratio On Young's Modulus Characterization Using Ultrasonic Technique By Modeling, Michael Onyetube
Effect Of Poisson’S Ratio On Young's Modulus Characterization Using Ultrasonic Technique By Modeling, Michael Onyetube
Electronic Theses and Dissertations
The past 27 years has witnessed a revolutionary growth in the progress of material development and application in almost all industry and business sectors, and this seems to be continuing even today. So many material-driven innovations have enabled the global spread in technology and improvements in capability, ranging from communications to aerospace and healthcare, to automotive and agriculture. Mechanical behavior of elastic materials is modeled by two main independent constants; Young’s modulus and Poisson’s ratio. An accurate measurement of both constants is necessary in most engineering applications, for example, the standard materials used for the calibration of some equipment, quality …
Fiber Orientation Prediction And Strength Evaluation Of Composite Spur Gears Reinforced By Discontinuous Fiber, Nawrin Jahan
Fiber Orientation Prediction And Strength Evaluation Of Composite Spur Gears Reinforced By Discontinuous Fiber, Nawrin Jahan
Electronic Theses and Dissertations
Composite materials have been extensively used for their important role in attenuation of components design, low specific weight, high mechanical performance, and excellent corrosion resistance offer significant advantages over metallic materials. These superlative properties can be attained by tailoring different material in an appropriate combination of the reinforcing phase (carbon fiber, alumina, etc.) and matrix phase (polymer, ceramic, metals, etc.). Carbon fiber reinforced composites are mostly used on intricate stress sensitive structures like wings of aero plane or gear. Amount of fiber, fiber type, and size of the fiber and the orientation of reinforcing fibers directly influence the mechanical properties …
