Analytical models have been developed for fracture propagation over the last several decades and are now considered with renewed interest; the range of their applicability varies for different materials and different loading conditions. Systematic experimental measurements are presented against an asymptotic prediction for the crack trajectory developing in a solids with small voids (or inclusions). The experiments also cover the dynamic regime, where new features involving crack kinking and roughness of the fracture surface occur.
