NiTi Fretting Fatigue Life Prediction Model under the Low Cycle Load

For fretting abrasion accelerating the fatigue failure of the materials,fretting fatigue is actually the result of the interaction of fretting abrasion and general fatigue.NiTi shape memory alloy has good wear resistance and anti-fatigue properties,which can delay the occurrence of the injury and expansion of the damage.To improve the original fretting fatigue life prediction model,fretting abrasion is introduced into the the fretting fatigue life model as an important factor.The result gets a reasonable and effective prediction model for the fretting fatigue life prediction.
