Hey,

i have to choose a fatigue testing machine for additive manufactured metal parts.

Materials would be generic metals such as stainless steel, inconel etc.

The goal is to create simplified woehler / SN curves in a short time.

How can i decide which machine fits best?

Im looking for advantages and limits of the different machine types such as servohydraulic, electrodynamic, resonant pulsators and ultrasonic testing machines.

Also what is the limit for my test frequency to not get false results?

Thank you
