Pevností analýza hyperelastických materiálů

Abstract

This master's thesis focuses on the study of hyperelastic materials, specifically examining the strength of a selected silicone. The work begins with a theoretical background, followed by a literature review aimed at identifying and analyzing failure criteria from approximately 20 sources. Subsequently, experimental strength tests were carried out on the selected material under various principal stress ratios. These experiments provided data that were used to validate finite element method (FEM) simulations. Within these simulations, various aspects of material behavior were investigated, particularly strength and fracture energy. The results of these simulations were processed and discussed in terms of their applicability and suitability.
