Abstract
Self-fracturing of solids during chemical transformations is considered, and a first quantitative model of this widespread phenomenon is proposed. The analysis begins by considering the equilibrium of a single crack, and proceeds with the behavior of an ensemble of cracks. This enables one to solve the ‘‘selection problem’’ for this pattern-formation process and obtain formulas for the rate of crack-network propagation and for the diameter of the resulting blocks.Keywords
