Abstract

Abstract: The fatigue life gaugekuresistance-fatigue respoilsc sensor,similar in appearance to a foil strain gauge. Principles of a newly devcloped fatigue life gauge are presetited; both the inethods and results are discussed regarding the calibration of its resistance change characteristic curve under constant alternating strain. amplitude and its hehavior in the presence of mean strain or varied alternating strain-amplitude. The experiment findings indicate that the fatigue life gauge possesses high fatigue response、repetitiveness and stability.

Key words: fatigue life, cyclic strain, resistors
