Friction Test Specimens That Will Be Used to Measure Nonlinear Damping and Stiffness

Abstract

The funds received from the AFOSR were to be used to 1) purchase materials and machine friction test specimens and 2) refurbish a Brown and Sharpe Coordinate Measurement Machine (CMM). The specimens were used in an initially Carnegie Mellon University (CMU) supported and then US Navy supported research project titled, "Physical Models of Friction Constraint and The Effect of Friction on Bladed Disk Dynamics." For the first year, the graduate student working on the project was supported by CMU as a Teaching Assistant. The AFOSR funds allowed us to make specimens and begin testing before we started getting Navy funding. The CMM machine allowed us to check the dimensions of the specimens that we had manufactured and characterize how wear affected the contact geometry.
