The paper presents the results of numerical modelling of fixed-end hot torsion testing for conditions characteristic of the STD 812 torsion plastometer. The material used for the tests was a hard deformable aluminium alloy in grade 5019. The FORGE 2011®, a finite element method-relying software program, was used for numerical modelling. The obtained numerical modelling results were compared with results obtained from an actual torsion test using the STD 812 torsion plastometer. The performed numerical analysis enabled the determination of the stress and strain states and the temperature in the investigated aluminium alloy. Numerical modelling of the torsion test carried out in accordance with real experimental testing conditions makes it possible to determine the representative area for possible metallographic examinations.Keywords: numerical modelling, hot torsion test, hard deformable aluminium alloy 5019
