A shakedown analysis of high cycle fatigue of shape memory alloys

摘要: Abstract Shape memory alloys (SMAs) are exploited in several innovative applications, experiencing up to millions of cycles, and thus requiring a fully understanding material fatigue fracture resistance. However, experimental methodological descriptions SMA cyclic response still incomplete. Accordingly, the present paper aims investigate SMAs under macroscopic elastic shakedown propose criterion for high cycle SMAs. A multiaxial based on multiscale analysis phase transformation between austenite martensite using rigorous framework standard generalized materials is proposed. The an extension Dang Van applied uniaxial data taken from literature. It distinguishes run out failure tests infinite lifetime regime. permits novel insight into development general also suggests further investigations completely understand behavior shakedown.
