Fracture properties of dolomite and prediction of fracture toughness based on BP-ANN

Abstract In this study, based on the digital image correlation technique, three-point bending tests were conducted on dolomite semi-circular bending (SCB) specimens, and the fracture properties of the SCB specimens, including crack opening displacement, apparent fracture toughness (K If) calculated...
