The utilisation of aluminium alloys in structural applications requires knowledge of their characteristics in the elastoplastic area. The deformation of alloys in this area can be described by the Ramberg-Osgood's equation. Tensile test results for AW-5083 and AW-2024 alloys are presented, and it is confirmed that strain hardening can reliably be described with Hollomon equation. Ramberg-Osgood equations are derived for these two alloys based on strain hardening indicators.
