DEF

A fluid described by the two-parameter rheological model of a pseudoplastic fluid, or a fluid whose viscosity decreases as shear rate increases.

[...] considérons que la pâte se déforme comme un fluide en loi de puissance [...]

CONT

Étendue au cas du fluide loi de puissance isotherme, la modélisation permet en outre de considérer l'effet du caractère rhéofluidifiant (shear thinning) et d'appréhender les raisons profondes de l'intérêt de cette technique pour la fabrication de composites à base de caoutchouc.
