Elastomers are widely used in academic as well as in industrial application. The present paper purpose is to
understand the mechanical and cyclic properties of elastomers. Moreover how the fillers added in elastomers affect the
mechanical properties and fracture behavior of the elastomers is discussed. Elastomers with two different grades of
fillers are taken for research work. Experimental tensile test is performed to model the elastomers as hyperelastic
material in software and to obtain the mechanical properties of elastomers. Constant amplitude fatigue test is performed
on both the elastomers to obtain the cyclic properties and cycles to failure. This experimental data is taken for Stress Life
Fatigue Analysis in FEA software to compute the Fatigue Life and Fatigue Safety Factor. Comparison of fatigue life and
fatigue safety factor is tabulated to understand the fracture behavior and fatigue phenomenon in elastomers.
