WebApr 14, 2024 · The strength decrease rate SDR focuses on post-peak phase of complete stress-strain curves in uniaxial compression tests, using the average stress decrease velocity to reflect the rockburst tendency degree of rocks. Compared with other non-energy indicators, these two indicators have the advantage of accurate calculation, and reflect … WebOn the basis of this critical review, three measurement methods are identified, namely (1) elastic deformation before fracture, (2) shape of post-peak stress-strain curves and (3) methods based on fracture mechanics theory, which have the potential to be further refined and unified to become the standard measurement methods of rock brittleness. how to open xfinity remote
