roches ne subissant pas d'amolissement

Explanation:
Strain softening and ductility

Because shear zones are characterised by the localisation of strain, some form of strain softening must occur, in order for the affected host material to deform more plastically. The softening can be brought about by the following phenomena:

grain-size reductions.
geometric softening.
reaction softening.
fluid-related softening.

"Effets amollissants de la déformation et ductilité[modifier]

Pour localiser la déformation dans une zone de cisaillement un processus d'amollissement (en anglais strain softening) doit affecter la roche pour la rendre plus ductile. Plusieurs possibilités sont envisagés :

la réduction de la taille du grain.
l'amollissement géométrique.
l'amollissement par réaction.
l'amollissement par fluides."
