摘要：

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 and numerical simulations are presented against an asymptotic prediction for the crack trajectory developing in solids with small voids (of circular and elliptical shape). The experiments also cover the dynamic regime, where new features involving crack kinking and roughness of the fracture surface occur. (C) 2015 Elsevier Ltd. All rights reserved.
