The fundamental aim of this study is to determine the influence of crack propagation speed on the out-of-plane displacement fields in the neighbourhood of a crack tip (i.e. on the size of the 3D effects zone). As the crack propagation is a complex process that involves the deformation mechanisms, the out-of-plane displacement measurement gives pertinent information about the 3D effects. We propose in this paper, to analyse the out-of-plane displacements fields for different crack velocities in brittle materials.
