On creep enhanced by a liquid phase Academic Article uri icon


  • The creep of porous KCl and of porous sucrose has been measured in the dry state, and saturated with aqueous solutions and with organic liquids. Creep is accelerated when there is solubility of the solid in the pore fluid, in a way which varies linearly with stress, and exponentially with temperature. Triaxial tests show that the creep is caused by the deviatoric stress. Existing models for liquid enhanced creep are reviewed and found to be deficient. A new mechanism is modelled and discussed. 1983.
