Experimental and Theoretical Assessment of PBGA Reliability in Conjunction with Field-Use Conditions
(Georgia Institute of Technology, 2004-04-09)
With the dramatic advances that have taken place in microelectronics over the past three decades, ball-grid array (BGA) packages are increasingly being used in microsystems applications. BGA packages with area-array ...
Information Modeling for Intent-based Retrieval of Parametric Finite Element Analysis Models
(Georgia Institute of Technology, 2006-10-23)
Adaptive reuse of parametric finite element analysis (FEA) models is a common form of reuse that involves integrating new information into an archived FEA model to apply it towards a new similar physical problem. Adaptive ...
Nondeterministic Linear Static Finite Element Analysis: An Interval Approach
(Georgia Institute of Technology, 2005-08-26)
This thesis presents a nontraditional treatment for uncertainties in the material, geometry, and load parameters in linear static finite element analysis (FEA) for mechanics problems. Uncertainties are introduced as bounded ...
Numerical Simulation of the Shock Compression of Microscale Reactive Particle Systems
(Georgia Institute of Technology, 2005-07-18)
The shock compression of Reactive Particle Metal Mixtures (RPMMs) is studied at the microscale by direct numerical simulation. Mixture microstructures are rendered explicitly, providing spatial resolution of the coupled ...
Modeling and Verification of Cutting Tool Temperatures in Rotary Tool Turning of Hardened Steel
(Georgia Institute of Technology, 2004-04-08)
The chip formation process in machining is accompanied by heat generation. The heat generated influences both the workpiece physical properties as well as the cutting tool. High temperatures accelerate tool wear and thermal ...
Implementation of the extended finite element method (XFEM) in the Abaqus software package
(Georgia Institute of Technology, 2009-05-18)
This work describes the implementation of the eXtended Finite Element Method (XFEM) in the Abaqus software package. A user-defined element was developed containing the analytical functions relating to homogeneous and ...
Influence of microstructure in rolling contact fatigue of bearing steels with inclusions
(Georgia Institute of Technology, 2009-04-06)
The use of bearings can be found in virtually all aspects of mechanical systems today. Reliability of these critical components is an important issue. Fatigue performance of bearings is a function of many factors, including ...
Parallel processing approach for crash dynamic analysis
(Georgia Institute of Technology, 1989-08)
Analysis of flexible fiber suspensions using the Lattice Boltzmann method
(Georgia Institute of Technology, 2008-07-08)
The characteristics of fibers suspensions depend on the properties of fibers, the suspending fluid, and fiber-fiber interactions. This thesis demonstrates the development and application of a novel coupled method (lattice ...
Influence of crystallographic orientation in normal and sliding contacts
(Georgia Institute of Technology, 2008-05-19)
The aim of this study is to evaluate a methodology for modeling the influence of crystallographic grain orientation on key parameters in normal and sliding contacts. The simulations of interfering cylindrical asperities, ...
