Original Abstract

The paper describes methodology of numerical simulation of fatigue crack growth under the constant amplitude and spectrum loading and its application on integrally stiffened panels made of 2024-T351 aluminium alloy using high speed cutting technique. Presented approach is based on the calculation of stress intensity factor function from finite element results, subsequent crack growth analyses were performed in NASGRO. For predictions of crack growth under the spectrum loading a sequence representing service loading of the transport airplane wing was prepared. Three crack growth models were applied: non-interaction, Willenborg and Strip Yield. Relatively large experimental program comprising both the constant amplitude and spectrum tests on integral panels and CCT specimens was undertaken in order to acquire crack growth rate data and enable verification of simulations.
