Abstract : This report describes work undertaken in an attempt to understand the implications of an idealised model for predicting the fracture of graphite under tension. In this model the graphite is represented as a regular lattice of grains each of which has an equal and independent probability of being cracked under an axial stress. The present study is restricted to a further idealisation in which the model is taken to be one-dimenional. Both an exact formula and an asymptotic approximation to it are derived for the probability of occurrence of one or more sequences of contiguous cracked grains of a given size or greater. (Author)
