5. Conclusions Cold drawn pearlitic steel wires (in the form of commercial prestressing steel wires) exhibit axial micro-cracking paths (i.e., local crack deflections) that represent a signal of locally anisotropic hydrogen embrittlement behaviour , even for low levels of stress triaxiality in the absence of stress concentrators such as cracks or notches. 6. Epilogue: A Picassian Approach The fracture path in heavily cold drawn pearlitic steel develops in mixed mode following a deflected or kinked crack path, so that it can be associated with the change of viewpoint of the cubist painting by Picasso (Fig. 3).
