Abstract
A fatigue strength diagram is used when we estimate fatigue strength under mean stress or residual stress. The most well-known is the modified Goodman diagram, which connects tensile strength and endurance limit with a straight line. However, a fatigue strength diagram of aluminum alloy is not obvious because aluminum alloy does not have endurance limit-especially at high temperature. Thus, we make up the generalized fatigue strength diagram at N cycles of aluminum alloy at high temperature, using the strength at N cycles instead of the endurance limit, and divide the straight line by fracture feature; plastic deformation and creep. In other words, the fatigue strength diagram of aluminum alloy consists of 3 regions.
