Its objective is to answer the recently raised question: Can we neglect the impact of
the hydraulically induced shear stress when using the elasticity equation, which connects the
fracture opening with the net-pressure? The estimations, given in the paper, show that the
answer is "Yes". The impact can be confidently neglected. Its influence is well beyond physical
significance, computational abilities of computers and practical applications of HF.
Keywords: hydraulic fracture, shear traction, elasticity equation.
