The three‐dimensional interaction of a crack front with particles is investigated under mode‐I loading. The J ‐integral is applied to characterize the crack–inclusion interactions. Numerical examples are presented, using 20 node, isoparametric finite elements, for the compact tension specimen and elastic materials. The J ‐integral is calculated for various moduli of the particles, distances of the crack from the interface and particle size. The problem of the crack penetrating a cluster of particles is discussed. © 1998 John Wiley & Sons, Ltd.
