Abstract: The invention involves a method for testing a damage tolerance property in an aluminum alloy part with the following steps:



measure at least one property representative of a the part's tensile strength;
use the property measured in step a) as input datum (xi) of a neural network estimator;
estimate, using the estimator, the representative property of the part's tensile strength; the method being characterized in that it includes:
consideration of an acceptance threshold and comparison of the property estimated at step c) to the acceptance threshold, taking into account a confidence interval;
based on the comparison:

consider that the part passes the test;
or consider that the part does not pass the test.
