Future trends for determination of rubberbehavior in lab applied for tires at simulation of real loading conditions in service

Original language description

The aim of this work was to describe the future trends in experimental laboratory characterization of fracture processes of rubber material used for tire application from the energy point of view, and to contribute to the establishment of efficient, however highly exact complex methodology for fracture investigation. Two very new experimental laboratory equipment and methodological processes have been introduced. These are able to characterize the fracture processes in rubber material over very broad range of tearing energies. It includes the estimation of the minimal tearing energy, necessary for the crack initiation as well as critical tearing energy, defining the total ultimate rupture. Introduction and capability of these methods was demonstrated on experimental investigation and estimation of fracture behaviour of fundamental rubber types, which were NR and BR. The determined data for the experimental analysis of rubber materials, used in this work, exactly corresponds with the previously evaluated data from the work done by Gent et al., which was done still in the 1964. Thus, receiving identical data over the broad range of tearing energy by using the new methods and equipment demonstrates the huge potential and efficiency improvement. The complex investigation, including the equipment, clearly can be labelled as the future trends in experimental laboratory tools, characterizing the fracture behavior of rubber material with respect to real loading conditions, applied on rubber products in the field.
