It is advisable to use new description methods using complex analytical mathematical relationships or numerical systems based on the Finite Element Method. The paper presents a method for evaluating the properties of materials with non-linear characteristics. Issues related to the experimental verification of the properties of viscoelastic materials are discussed. The methodology for describing the features and phenomena occurring in hyperelastic materials, based on analysis in the system, is presented. Designing machine elements made of plastics and composites leads to a number of new issues, in particular the assessment of strength in the case of hyperelastic properties. It is advisable here to use new description methods, i.e., complex analytical mathematical relationships or numerical systems based on the Finite Element Method containing hyperelastic material models. A 3D CAD system, e.g., CATIA, SolidWorks, AutoCAD Inventor, UNIGRAPHICS, can be used as a preprocessor. The values of the model parameters were adopted using the results of experimental tests performed for the purposes of the work. (…)
