The article presents the procedure for the experimental and theoretical estimation of fracture toughness in salt rocks in testing of samples with wedge-shaped cut and by numerical modeling of the tests in ANSYS. The values of the stress intensity factor and the energy release intensity factor in tensile fracturing are presented for salt rocks of the Upper Kama Potash Salt Deposit.
