The Ruiz criterion is more simple and useful than the prediction model based on multi-axial fatigue failure. The fretting damage prediction at the upper split of the marine diesel engine’s connecting rod is compared to the actual inspection result taken after 20,000 running hours.

The machined mating surfaces will rub together, corrode and wear away (this is known as fretting). Once this has happened the alignment of the engine running gear will be destroyed. Loose tie bolts will also cause the transverse girders to bend which could lead to cracking, and main bearing misalignment.

Fretting - Wikiped...

Fretting fatigue. Fretting decreases fatigue strength of materials operating under cycling stress. This can result in fretting fatigue, whereby fatigue cracks can initiate in the fretting zone. Afterwards, the crack propagates into the material. Lap joints, common on airframe surfaces, are a prime location for fretting corrosion.

The engine must be securely fixed into the ship. As the engine turns the propeller, the propeller tries to push or thrust the propeller shaft and engine crankshaft forward into the ship. The thrust bearing which is situated at the aft end of the engine transmits this thrust from the crankshaft to the bedplate.

This fatigue crack initiation mechanism differs from normal fatigue process in alternating tensile stress without fretting. 4. Marine main engine crankshafts and its maintenance. Marine main engines of large ships generally work at low medium speeds and experience a large number of load cycles during their service life.
