Mechanical properties and fracture surface roughness of thermally damaged granite under dynamic splitting
• The effects of thermal damage and the loading rate on dynamic splitting mechanical properties and fracture surface morphological characteristics of granite were determined. • The surface roughness index Z2 in the axial and radial directions of the Brazilian splitting sample was calculated. • Prediction models of dynamic splitting parameters based on Z22r are proposed.
