ANSYS software Fatigue sensor Health monitoring U-notch sensorAbstract
Fatigue sensors are used as Structural Health Monitoring (SHM) mechanisms to detect
damage on struc- tural components before any failures occur. In this study, a U-notched
fatigue sensor was designed and analyzed to predict the fatigue life before catastrophic failure
occurs. The ANSYS workbench software and 7075-T6 aluminum alloy were used to model
and analyze our U-notch type fatigue sensor. The sensor model consisted of four beams of
305 × 76.2 × 1.6 mm (length × width × thickness) dimensions with different fatigue U-notch
radii. It was observed that fatigue life increased with an increase in the U-notch radius.
However, the value of the maximum equivalent stress decreased with an increase in the notch
radius. In addition, fatigue damage occurred around the U-notch radius when the U-notch
radius was equal to or less than 6.4 m
