    Smart predicative methodology for testing of tire behaviour in lab scale

  • Original language description

    In practice, tires are exposed to complex dynamic loading conditions caused due to car´s kinematic energy, profile of road surface as well as influence of ozone concentration, solar radiation, different temperature etc. These complex processes constitute the initiation of micro-cracks in tire, which is the fundamental fracture element of rubber-matrix responsible for tire tread wear, proceeding of fracture processes as well as of total tire failure. The tests and determination of tire failure respective fatigue lifetime of rubber matrix used for tire applications in the field are time and money consuming and thus the effective testing methods in laboratory condition is highly appreciated. The aim of this work is to introduce a methodology leading to accelerated prediction of rubber matrix fatigue lifetime. The complex methodology is fundamentally based on determination of a minimum energy requirement for the rupture of chains in a crack of rubber matrix, which is known as intrinsic cutting strength and energy necessary for crack growth under increasing dynamic loading conditions. Finally the correlation of the methodology used with the fatigue lifetime has been discussed.
