Part II: Consolidating contact phase — Poroelastic effect

Abstract The lubricated clutch engagement behavior of two annular disks, one of which is covered with a layer of porous material, was analyzed at the consolidating contact phase based on the theory of poroelasticity. The porous friction material was treated as a porous elastic sponge saturated with a viscous fluid. Results are presented in terms of the relations of deflection versus time for various geometric and material parameters. Comparison made between analysis and experiment at squeeze film and consolidating contact phases indicates good qualitative agreement. The overall disk engagement behavior of the present model is also discussed.
