Abstract
Chalk behaves with time dependent deformation when subjected to a load. We review a previously published data set from high pressure oedometer tests and apply a friction factor corresponding to the friction between solid and pore fluid. The friction factor is the Biot critical frequency used in acoustic theory to discriminate between the high and low frequency domains. By doing this we show how test results from dry, oil, and water saturated chalk can be combined in one simple expression.
