Abstract

An experimental and numerical study is presented of the mechanical behavior during the conventional tensile test of three different aluminum alloys extensively used in aeronautical applications: 7075 T7351, 7050 T7451, and 2024 T3. A set of experiments has been carried out with cylindrical specimens in order to obtain the elastic and hardening parameters that characterize the material response. Moreover, a finite element large-strain elastoplasticity-based formulation is proposed and used to simulate the deformation process during the whole test. Finally, the results obtained with the simulation are experimentally validated.
