The paper discusses and presents a hyperelastic incompressible material described by Zahorski potential. The numerical example comparing effective stresses in a cylinder made of Zahorski and Mooney-Rivlin materials was included. The analysis was made in the ADINA software. Conclusions summarize numerical calculations and demonstrate the differences that suggest the use of Zahorski material for rubber and rubber-like materials subjected to large deformations.
