The rock damage and strength study based on ultrasonic velocity

    Graphical Abstract
    • Abstract
  • Based on damage mechanics, the initial damage variable of rock is defined as its ultrasonic velocity, when there is no loading on it. The damage evolution equation was set up by the ultrasonic properties model for rock under loading.The rock strength was predicted by the ultrasonic velocity of rock.
