5. Fracture of cold drawn pearlitic steels: A Picassian Approach The crack paths in heavily cold drawn pearlitic steels develop in mixed mode following a deflected crack path (Toribio, 2018c), so that it can be associated with the change of viewpoint of the cubist painting by Picasso (Fig. 7).

6. Hydrogen embrittlement of cold drawn pearlitic steels: Between Donatello and Michelangelo With regard to the hydrogen damage topography (HDT) in the form of tearing topography surface (TTS) in slightly drawn pearlitic steels, it could be associated with the Michelangelo stone sculpture texture (MSST) shown in Fig. 8 for the Pietà di Firenze and the Pietá Rondanini (Toribio, 2017b, 2017c). In the matter of the HDT in the form of enlarged and oriented TTS (EOTTS) in heavily cold-drawn pearlitic steels, it would resemble the Donatello wooden sculpture texture (DWST) shown in Fig. 9 for the two magnificent works of the Penitent Magdalene and the Saint John the Baptist (Toribio, 2017b, 2017c).
