The research work of this dissertation consists of two
parts. The first part is the application of the finite
element method (FEM) to nonlinear frictional contact
stress analysis of full 3-D gear coupling models. To the
author=92s best knowledge, no published work using the
full 3-D finite element model of gear coupling is
available in the literature. FEM models and processes have
been developed in this thesis for the analysis of gear
coupling with misalignment. The developed processes can be
employed as a template to other gear models with different
design parameters. They can also be expanded in more
complex analyses such as fracture and thermo-elastic
analyses. The second part of the research is on the
development of two new boundary element algorithms for
solving 3-D, frictional, and linear elastostatic contact
problems. The main contribution of this research is that
solving 3-D boundary element models with non-conforming
discretizations becomes possible for the first time by
using the proposed algorithms. These algorithms are
implemented in a new 3-D boundary element code using C++
and verified using several numerical examples. For the
models studied, the results using the new boundary element
algorithms match well with the finite element results and
clearly demonstrate the feasibility of the new boundary
element approach for 3-D contact analysis
