Abstract: The invention relates to a thin metal sheet which is made of an alloy based on substantially recrystallized aluminum and which has a thickness of 0.25 to 12 mm, the alloy comprising, in percent by weight, Cu 3.4-4.0; Mg 0.5-0.8; Mn 0.1-0.7; Fe #0.15; Si #0.15; Zr #0.04; Ag #0.65; Zn #0.5; inevitable impurities #0.05 each and #0.15 in total, the remainder consisting of aluminum. The invention also relates to a process for manufacturing such a metal sheet and to the use thereof as a fuselage panel or sheet metal for the production of composite products such as fiber metal laminates (FML) for wing or fuselage applications in the aeronautical industry.

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.-

Abstract: The invention relates to a sheet metal plate (10) for creating flooring (30), in particular for industrial vehicles, having on its upper surface (11) a plurality or raised patterns, each raised pattern comprising one or more protruding portions (20), the raised patterns being arranged periodically, discreetly and in orderly fashion, the height h of the raised patterns being between 0.3 and 3 mm, characterized in that the plate has, on its lower surface (12), which is intended to be bonded to a support member, a rough surface the roughness Rmax of which is between 10 μm and 250 μm. The invention also relates to the method of producing said plate and the use of said sheet metal plate for creating flooring for industrial vehicles, preferably flooring for refrigerated vehicles.
