On the impact of tangential traction on the crack surfaces induced by fluid in hydraulic fracture: Response to the letter of A.M. Linkov. Int. J. Eng. Sci. (2018) 127, 217-219

In response to the “critical comments” by Dr. Linkov concerning our publication Wrobel et al. (2017), we will demonstrate here the major faults in the logic of his arguments. We uphold the conclusions from Wrobel et al. (2017), in particular that the hydraulically induced shear stresses on the fracture faces may play an important role in the HF process and its numerical simulation, especially in the viscosity-dominated regime.
