FUNDAMENTAL STUDY ON MUD-FLOW (IV)

The relation between stress and strain for the mixture consisted of clay and water wasexamined as the fundamental step for the approach to the physical character of mud flow.Two types of rotational viscometer, the cap rotation type and the bob rotation type, were usedin the mesurement.Through the experiment, it was disclosed that the relation between stress and strain forthe mixture follows to the power law or Biogham's law. Although the conditions goveringthese laws are not yet clear, it seems to be due to the construction of micelle.
