Capability of load-time history reconstruction and fatigue crack growth rate estimation for 2024-T3 aluminium alloy on the basis of fractographic analysis
The subject of the paper is the considerations of the capability of load-time history
reconstruction for the component under variable amplitude loading and fatigue crack growth rate
estimation for the 2024-T3 Alclad aluminium alloy on the basis of microfracture analysis. For this
goal three variable amplitude (VA) load sequences with multiple overloads and differing from the
level of load sequence complexity were applied. These loads are employed when simulating the
fatigue behaviour of aeronautical alloys. To reveal the load sequence effect on crack growth behaviour
the microfracture analysis were provided by means of TEM microscope
