    Abstract

    An experimental procedure for nondestructive, specimen-specific measurement of membrane penetration volume change is presented. The procedure involves measurement of the annular volume between two membranes as an outer ported membrane is “consolidated” over the deformed surface of an inner membrane. With minor adjustments for the effects of membrane thickness and pore-pressure change, the double membrane procedure yields the membrane penetration volume change behavior of the inner membrane. The procedure is conducted in such a manner that the effective stresses in the specimen remain unchanged, allowing the specimen to be tested after its membrane penetration characteristics have measured. Agreement with measured membrane penetration behavior has been very good.
