Brief abstract:

This project aims at developing a non-contact stress-strain measurements of small bearing cages under operation. the project utilizes the thermo-elasticity principles to correlate the temperature maps under cyclic loadings with the stress behavior of the heat affected zone of bearing cages.  


Impact:

Accurate predictions of the stress fields of bearing cages helps in establishing their failure  stress and understand their behavior at the heat affected zone.

Project schedule:

Initiated and completed in 2009

Preliminary results:

Accurate 2D maps of the stress fields within the heat affected zone of bearing cages.
