Abstract
The paper presents development of crack paths in aluminium alloy 2024. Fatigue tests were carried
out for specimens with rectangular cross-section. The specimens were put to bending at controlled energy
parameter amplitude and bending moment amplitude. The proposed method of conducting research with the
controlled energy parameter has been presented in [1]. The energy parameter model proposed by Macha has
been used in the tests. Tests with controlled energy parameter amplitude allow observing crack growth
depending on maximum shearing stress surface. Tests with controlled bending moment amplitude allowed
observing two types of crack paths.
