The paper presents analytical and numerical determina-tion of the equivalent stress and strain of the open section thin-walled ‘’ cantilever beams loaded with torsion. Ana-lytical calculation was used to calculate the equivalent stress and strain values for the model encastred across the entire cross-section at one end, while the other end is free (model 1). The finite element method is applied for the calculation of the same ‘’ cantilever beam model exposed to torsion, and the stress and strain values are obtained by numerical calculation. Numerical simulations have been performed using KOMIPS software. Analytical and numerical results are compared and discussed. In this paper, a numerical model for constrained torsion is also created in ABAQUS® and SolidWorks® software. A cantilever beam with an omega profile is encastred at one end, while at the other end there is a welded plate (model 2). Numerical models are created, and static calculation is done using the finite element method.... The zones of stress concentration are identified and presented. Finally, the equivalent stress values of models 1 and 2 are compared. Conclusions obtained by examining this type of structures may be involved in the design process of new similar structures. The findings obtained during the implementation of this work can be directly applied to iden-tify the behaviour of real structures in their working condi-tions.
