can you tell me the rheology of Casson plastic?
Thanks !

srikrishnan,
Such a simple question could have many answers. Please elaborate on what you need, but first, did you Google "casson plastic viscosity" and look at http://ciks.cbt.nist...SP946/node8.htm ?

Thank you sir for your kind response ,well i actually required to know how is will be its shear stress vs velocity gradeint graph ,whether its time dependent or not?
pardon me for the late reponse i was out for writing my term exams

It is not time dependent. It's velocity gradient graph looks similar to Bingham Plastic, except it is not linear. It has a yield stress and is a square root relationship.
