Progress Report

DESCRIPTION

This report outlines the current progress on the analysis of the hybrid spur gear created by Brent Ewing. Key updates include the modeling of adhesive properties using linear cohesive elements, consideration of each lamina's three angles rotated by 60 degrees, and the completed tie constraints. Bending stress calculations have been performed on a single tooth and the whole gear using FEA. Additionally, the report details the impact of lightening holes in the design. A thorough analysis will be compiled to populate the final report.
