Abstract
Magistrsko delo raziskuje postopek numeričnega modeliranja hiperelastičnega materiala z uporabo enoosnih napetostnih testov ter dinamične mehanske analize, v primeru prednapetega hiperelastičnega materiala. V delu sta bili izvedeni statična in dinamična numerična simulacija sestava z metodo končnih elementov. Spremljali smo vpliv vpetja dveh različnih vzorcev na ekvivalentni Youngov modul elastomerne podložke. Rezultati so validirani z meritvami eksperimentalne modalne analize na stresalniku.

Title:Numerical modelling of hyperelastic material and effect on natural frequencies
Abstract:
The Master's thesis explores the process of numerical modeling of a hyperelastic material using uniaxial stress test data and dynamic mechanical analysis, specifically in the case of pre-tensioned hyperelastic material. In the thesis, static and dynamic numerical simulations of the assembly were performed using the finite element method. We monitored the influence of the mounting of two different samples on the equivalent Young's modulus of the elastomer washer. The results were validated against measurements from experimental modal analysis on a shaker.

Keywords:elastomer, dynamic mechanical analysis, nonlinearity, hyperelasticity, modal analysis, finite element method
