We discuss the Hydraulic Fracture (HF) model introduced in [1] accounting for the hydraulically induced shear stresses at the crack faces. The model utilizes a general form of the boundary integral operator alongside a revised fracture propagation condition based on the critical value of the energy release rate. The tip asymptotics of the revised model is always consistent with that of the Linear Elastic Fracture Mechanics. We have found that energy release rate criterion takes a more general form in this case and, in fact, plays the role of a natural regulariser in the numerical simulations. As a result, the hydraulically induced tangential tractions may play a significant role in the small toughness and viscosity dominated regimes of crack propagation, while for other regimes the reported results are close to those obtained in the classic model. We have also found that, in case of small toughness or viscosity dominated regimes, the crack redirection angle may change rather significantly for a mixed mode loading [2]. Certain aspects of the recent discussion on the topic [3-5] will be presented and commented. The potential of the revised formulation in tackling some challenges of HF modelling will be demonstrated.
