... of poroelasticity on the contact stress and the transient indentation force response is then discussed. The asymptotic behaviors for the normalized transient force at early and late times are derived. Though derivation of these fully coupled solutions requires the aid of a variety of mathematical techniques...

... (? 2/3 ) solutions for the fracture aperture co-exist near the fracture tip. Depending on the ratio of viscous dissipation and fracture resistance, the region for the validity of each tip asymptote varies. In this paper, we developed a 2D displacement discontinuity based hydraulic fracture propagation...

... or viscous regimes of propagation by using the corresponding asymptotic solution at the tip element. Since either the viscous or toughness asymptote is used, the intermediate regime is not described accurately. To deal with this problem, this study aims to implement the intermediate asymptotic solution...
