sent back to the ‘Cycle’ object. The new crack length is then calculated followed by checks to determine if one of the termination conditions (e.g. target crack length achieved, crack arrest) is met. If a termination condition is established, the ‘Cycle’ object is passed to the reporting object and the calculation stopped. If a termination condition is not met, the cycle pointer is incremented and the process continued. The ‘Cycle -by- Cycle’ looping algorithm is summarised in Fig. 3.
