Smoke and Mirrors: Ultra-Rapid-Scan FT-IR Spectrometry

This false color plot shows the von Mises or total stress in a cross-section of the aluminum disk when operated at 30,000 rpm. The peak stress corresponds to approximately 35 MPa. The yield point of aluminum should be at least twice this high, and if there are no cracks in the disk, the ultimate tensile strength should be about 14 times higher.
