This project builds upon the earlier work done in the group (Ratsmiba, Tsunoda, Ng, Liang, Asare) which measures the cyclic fatigue crack growth for specific tearing energies in a variety of elastomer compounds using simple test pieces. Then finite element techniques are applied to calculate the tearing energy relationships for cracks of different sizes located in real components. From this it is possible to calculate the fatigue life of the component. The main aim of this current investigation is to model inter layer fatigue peeling failure in aircraft tyres.
