摘要: This paper presents experimental studies on low cycle fatigue (LCF) life of super-elastic shape memory alloy (SESMA) wires. The effect frequency the loading and amplitude strain has been studied individually. Various frequencies have considered to study frequency, by keeping constant. From data, it was found that LCF SESMA reduces with increase in frequency. also studied, cycled at lower net more than one higher strain. Further, plastic accumulation is samples tested loadings. modulus austenite be large independent loading. martensitic unloading same for all minimum amplitudes.
