Steady-state response of the contact traction tn and contact interface fluid pressure p for sliding of a rigid impermeable cylinder over a rectangular slab of biphasic material, in a plane strain analysis. The slab (width = 40 mm, height = 1 mm) is bonded to a rigid impermeable substrate. The model (not shown) has 20×1024 elements, with a dual bias mesh along the height. The applied load intensity is 1 N/mm. Results are shown for three different Peclet numbers (representing the ratio of sliding velocity to characteristic diffusive velocity of interstitial fluid flow): (a) Pe = 10-2; (b) Pe = 10 0; (c) Pe = 102.
