Status of Analyses


Two ABAQUS load cases have been added (at request of
Professor) since last progress report: 2D AGMA Gear
Bending and 2D AGMA Contact Stress.
With the exception of the above analyses, all other
analyses are complete.


Mesh convergence studies still need to be completed.
Stress distributions and data for the various analyses are
shown in the next slides.
