Abstract
A method for constructing a modified Haigh-Goodman diagram for flawed components is proposed based on the approximation by El Haddad for the crack growth threshold diagram, taking into account the influence of the stress ratio on the fatigue limit of the unflawed material as well as on the linear-elastic crack growth threshold. The modified Haigh diagram uses a minimum of easily obtainable material parameters and permits an easy application of damage tolerant design concepts when dimensioning for infinite fatigue life.
