Abstract
Two procedures for the fatigue analysis of elliptic and semi-elliptic crack s proposed in engineering guidelines are compared. The "original" procedure follows the growth of an actual crack, the "simplified" one considers the growth of a recategorised strip (tunnel) crack. The conservatism of the "si mplified" procedure is investigated in an extensive computer study. (C) 200 0 Elsevier Science Ltd. All rights reserved.
