The evolution of a crack front under mixed mode loading (I+III) is studied using a phase field model in 3 dimensions with no stress boundary conditions. As previously observed experimentally in gels, there is a relaxation toward a geometry where without any front fragmentation even for high values of the initial mode mixity . The effects of the initial condition are studied and it is shown that irregularities in the initial slit can lead to front fragmentation for smaller values of the ratio as is observed in experiments.
