  • Investigating Strength Of Materials By Application Of Mechanical Stress (AREA)

Abstract

PURPOSE: To detect fatigure strength by processing two comparison values with AND circuit to which being applied these two comparision values obtained as follows; one is comparison between stress signal detected in the tested parts material and its delayed signal; the oterh is comparison between stress signal and reference value.
