In this paper the dynamic indentation test method, which is not often used, is discussed. The goal of the paper is to consider the possibility of applying a dynamic indentation test method to investigate rubber materials. The basic equations for the determination of the viscoelastic characteristics of a material are presented and the experimental set-up is described. The Kelvin–Voigt model is used to describe the characteristics of a material. Experimental and theoretical curves for velocity, force and penetration in the indentation process are compared for rubbers with different hardness. A semi-empirical relationship between the Shore hardness and the rigidity c was derived.
