The design and construction of a flange-mounted ultra-high vacuum compatible fatigue apparatus using a piezoelectric actuator is described. This apparatus is capable of operation under ambient pressures down to 10 -9 Torr. Push-pull fatigue tests can be performed under load, total strain, and plastic strain control at frequencies up to 100 Hz. Control of the fatigue tests and data acquisition are done using standard fatigue control electronics and software.
