5. Resembling Picasso, Larionov and Goncharova The afore-said anisotropic behaviour in air, HAC and LAD conditions (with deflected polygonal cracks and mixed mode propagation ) resembles the cubist painting by Pablo Picasso (Fig. 8), not only because of the broken line after crack deflection/deviation, but also on the basis of a real change of viewpoint in painting .

Paintings by Picasso: Les Demoiselles d’Avignon (detail) (left) and Woman in Hat and Fur Collar (Marie- Thérèse Walter) (right) Such an anisotropic behaviour in the form of sudden changes in crack paths and very different lines ( or rays ) marking propagation direction also resembles the rayonist painting by Mijail Larionov (Fig. 9) in which many straight lines (many rays or directions) define the painted object.

The different propagation directions defined by the crack paths in progressively drawn pearlitic steels also evoke the painting by Natalia Goncharova (Fig. 10), the other key member of the artistic movement called rayonism , launched on the basis of modern Physics in the XX and the discovering of X rays.
