    i want to ask that what is the difference between anelastic, inelastic, viscoelastic, viscoplastic deformation...
    please tell that which depend upon time or not
    please tell that which shows recoverable or unrecoverable deformation....
    I need immediate help CEAN'S

    inelastic means plastic, and it means that a particular material will not return to its original shape once the deforming forces are removed.


    viscoelastic and viscoplastic seem to be associated with fluids. i am coming across them for the first time.

    but from what i can make out from the name, it seems to be the change of viscosity of a fluid with respect to temperature.

    if temperature of fluid increases, then its viscosity decreases. now there can be two cases, when this fluid is cooled:

    1) on cooling if the fluid gains back its viscosity, then it may be viscoelastic.

    2) but even on cooling if the original viscosity is not obtained, then the fluid may be viscoplastic.

    (PS: i not sure of it though).
    Are you sure? This action cannot be undone.
