Abstrakt EN: In this contibution, a model of changes in mechanical properties due to cyclic loading is pre- sented. The particular mechanical property in question is nonlinear quasistatic stress-strain behavior. It is as- sumed that this can be satisfactorily described by the Ogden hyperelastic model at any point in the cyclic load- ing. Therefore, the experimental program consists of long-term harmonic loading that is interrupted by static cycles at various points. These static stress-strain curves are then used to identify the parameters of the Ogden model and an expression is suggested that gives the approximation of the Ogden parameters as a function of the number of cycles and parameters of the harmonic loading.
