accuracy. Second, the crack length can not be represented accurately, which leads to a higher truncated error. From the point of view of modelling simplicity, the algorithm of the particle deletion technique is simpler than the interaction deletion technique. This led to the implementation of the particle deletion method being straightforward. On the other
