Abstract
We introduce a description of the early stages of the fragile rupture of disordered materials. The concentration of stress in the neighbourhood of a crack is treated as an attraction for the nucleation of a crack, whereas the distribution of failure strength in the material gives an effective repulsion. The balance of these two terms gives rise to a very simple way of analysing size effects, in relation with the distribution of failure strength. A few quantitative predictions are presented.Keywords
