Document Type and Number:
WIPO Patent Application WO/2014/204032
Kind Code:
A1
Abstract:
The present invention relates to an indentation fatigue test module mounted on an indentation tester applied to an indentation fatigue evaluation system. According to an embodiment of the present invention, an indentation fatigue test module mounted on an indentation tester applied to an indentation fatigue evaluation system has an actuator which is a piezoelectric-type actuator, the actuator moving an indenter and applying an indentation load, thereby advantageously applying loads repeatedly at a frequency of up to 100Hz and, at the same time, implementing 50mN-grade load resolution and 10nm-grade displacement resolution.
