... namely, linear Mohr-Coulomb and nonlinear Hoek-Brown criteria are used. However, the failure envelopes from the two criteria deviate much, especially, at low confinements. The main motive of this investigation is to understand the stress state around an opening. An underground copper mine of Hindustan...

... Abstract For the mixed-mode fracture on an original crack plane, the fracture criteria are usually based on the coupling of K I / K IC and K II / K IIC . Extended to general potential fracture planes, they become K I ( θ )/ K IC and K II ( θ )/ K IIC . Specifically, three forms...

A general trend of compression strength and the Young s modulus increase with the increasing strain rate can be observed. And it is found that, overall, fitting results with Hoek-Brown (HB) criteria are more accurate...
