| Abstract: | The tests of granite failure under coupled static - dynamic load were made on the SHPB test system. Damage and fracture property of granite under coupled static - dynamic load had been analyzed based on the experi- mental results. The results show that the fractal dimension has significant effect relating to strain rate of samples. The width of crack had been calculated using opening - displacement method. |
