The stress margin is one of the fundamental margins for a structure, which also goes to determine the fatigue life / damage tolerance of the structure depending on the nature of the stresses. Generally components are loaded multiaxially , hence combining stresses to assess failures is a must. Prestress due self weight or joint or heat treatment also must be accounted for, apart from other obvious sources.
Example Optimum shaft sizing from stress perspective.
