Graduate Theses, Dissertations, and Problem Reports
Particulate metal matrix composites (MMC) exhibit higher stiffness, strength and wear resistance compared to metal alloys. They exhibit superior compressive and buckling strength because of their higher plastic modulus. MMC's can operate at very higher temperatures than fiber-reinforced polymer composites. Their isotropic behavior and forming ability by conventional methods makes them a better choice for low-cost applications. They have good thermal conductivity, high electrical conductivity and low thermal expansion.;The main objective of this study is to predict numerically the stress distributions around the hole in a bolted joint made of particulate metal matrix composite and to investigate the associated load …
Characterization Of New Particulate Mmc Materials And Bolted Joints Through Applicable Astm Standards, Vinu Zacharia Mathew
Characterization Of New Particulate Mmc Materials And Bolted Joints Through Applicable Astm Standards, Vinu Zacharia Mathew
Graduate Theses, Dissertations, and Problem Reports
Particulate reinforced metal matrix composites (PRMMC) comprise a new class of materials whose properties can be adjusted to suit a particular application. The main purpose of producing PRMMC is to achieve lightweight materials with added properties like high stiffness, high ultimate strength and hardness.;In this study we deal with PRMMC manufactured by a novel technology involving the pressure less infiltration of aluminum into a mass of ceramic reinforcement particles. Basic tests like tension test, three point bending test, hardness tests and coefficient of thermal expansion are conducted according to the ASTM standards in order to characterize the material. All these …

Oil well industry has been using hydraulic fracturing to open new channels and thus increase well productivity. Materials known as Proppants are injected into the fracture to keep the channels conductive after the applied hydraulic pressure is removed. But the proppants used to date are often crushed under the influence of rock closures, which leads to clogging of the channel.;The main objective of this study was to model a material that would be able to withstand the rock closure stresses and also remain conductive. A three-dimensional finite element model was developed to study the effects of the shape and the …

Modeling Of An Aluminum Reduction Cell For The Development Of A State Estimator, Philip Biedler
Graduate Theses, Dissertations, and Problem Reports
Electrolytic cells are used to produce aluminum from alumina ore. These cells use a carbon anode, a cryolitic bath, and a carbon containment vessel, which also serves as the cathode. The process is not completely understood because of the limited number of measurements and its complexity.;A finite element model was developed that simulates the electrical, thermal, and chemical phenomena occurring within the cell. The model was verified by comparing its output to data presented in the literature, and by comparing its output to data gathered from operating reduction cells at Century Aluminum in Ravenswood, WV. The model was used to …
