Development Of A Stable Tetrahedral Finite Element For Metal Forming Analysis., V B. Rachakonda Jan 1994

Development Of A Stable Tetrahedral Finite Element For Metal Forming Analysis., V B. Rachakonda

Graduate Theses, Dissertations, and Problem Reports (ETD)

A nonlinear 'velocity-pressure' mixed finite element formulation for three dimensional rigid-viscoplastic analysis of metal forming problems is presented. It adequately takes into account the nonlinear material behavior and the large deformations that occur during metal forming operations. A ten-noded tetrahedral finite element with a quadratic interpolation in velocity and linear interpolation in pressure is used to discretize the domain of the deforming body. The salient feature of the formulation is the enforcement of the incompressibility requirement necessitated by the use of the rigid-viscoplastic constitutive law by modifying the constitutive equation to include a pressure variable and adding an additional constraint …

Interpretation Of Data From A Horizontal Heat Transfer Tube In A Bubbling Fluidized Bed., Ali Ihsan Karamavruc Jan 1994

Interpretation Of Data From A Horizontal Heat Transfer Tube In A Bubbling Fluidized Bed., Ali Ihsan Karamavruc

Graduate Theses, Dissertations, and Problem Reports (ETD)

Prior calculations of heat transfer coefficients for an experimental horizontal tube in a bubbling fluidized bed have assumed that the heat conduction through the tube wall is one dimensional. However, a comparison between one dimensional (1D) and two dimensional (2D) analyses and comparing them with experimental data shows that there exists a significant difference between 1D and 2D calculations. The analysis was accomplished by solving the unsteady 1D and 2D heat conduction equation across the tube wall numerically. The boundary conditions were taken from the temperature data measured at five different locations around the horizontal tube simultaneously. A correction factor …
