Fatigue Enhancement of Undersized, Drilled Crack-Stop Holes

A new treatment will be attempted using Piezoelectric Impact Compressive Kinetics (PICK) techniques. The technique being developed at the University of Kansas uses knurled heads of an end effector to essentially cold work the surface of a drilled hole at finite points. Like shot peening at ultrasonic frequencies, the PICK method concentrates the energy of an end effector in a tiny area which is rotated within a hole. An internal-only report was produced. This project is part of a pooled fund project that will produce a public report.
