  • ABSTRACT: A temperature-dependent constitutive model of 2024-T3 high-strength aluminum alloy is proposed, applying the "flow stress" concept. The model defines the relationship between the stress and strain tensors for a point of the surface layer subjected to surface plastic deformation (SPD). The model is developed on the basis of combined approach, which includes experimental test (identification test) and inverse finite element analysis of the experimental test. The developed constitutive model takes into account the temperature influence on the surface and sub-surface layers of 2024-T3 high-strength aluminum alloy in the range of T = (50 ÷ 300) ° C . The model can be used for numerical simulations in order to study the stressed and strained state of components subjected to SPD and consequent mechanical and/or temperatural loads
