Fretting Fatigue Characterization of Steel Bolted Connections
… small amplitudes at the same time. Slip-critical bolted connections are commonly used in repetitive loading applications and are susceptible to fretting fatigue failure. Among the many factors that can affect the fretting fatigue life of the bolted connections, bolt preload and surface finish are …
