Abstract

An experimental activity was performed to collect test data on the fatigue crack propagation in various types of specimens, within the DaToN research project, partly funded by the EU in the FP6 programme. Only one general configuration was used, i.e. flat panels with two blade stringers, with different options for the manufacturing processes, that could be integral or welded. The purpose of this test activity was to obtain useful results for the validation and calibration of prediction methodologies, also developed in the same DaToN research project. A wide experimental programme was defined and performed by many laboratories; the materials investigated were 2024-T3 and 6056, welded in the T4 or T6 conditions. The main results are here presented and commented, both for what concerns the fatigue crack propagation tests and the residual stress measurements.
