Two procedures for the fatigue analysis of elliptic and semi-elliptic cracks
proposed in engineering guidelines are compared.
The "original" procedure follows the growth of an acutal crack, the
"simplified" one considers the growth of a recategorised strip (tunnel)
The conservativism of the "simplified" procedure is investigated in an
extensive computer study.
