Apr 28,2010·1018 mild steel and 304/316 cres should theoretically have some fatigue endurance limits.But establishing what those limits are might be tough.Values like endurance limit and fatigue life for a particular material and structure can vary widely based on many factors.In the end,fatigue life mostly boils down to a statistical value that asp.infoPAPER OPEN ACCESS Fatigue and Fracture Behaviours ofgood fatigue behaviour and better fatigue properties near to base material than what the FSW were.The endurance limits were 81 MPa and 71 MPa for FSP and FSW joints respectively and 87 MPa for base metal.1.Introduction AA5083 Aluminium alloy were used in the shipbuilding manufacture for more than fifty years [1].Due
