✦ Synopsis

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.

## Introduction Recently the authors have been involved with elastoplastic finite element computations of the stress and strain fields around crack tips, with a view to establishing a suitable fracture criterion for crack propagation under these conditions. A particular feature of this class of pr
