4.2. ‘ Rapid Integration ’ looping algorithm The ‘Rapid Integration’ looping algorithm is based on the method proposed by Brussat (1974). According to this method, the crack length is discretised over a number of small intervals and the crack growth rate is calculated at distinct integration points along the propagation path.
