Fractal and Fractional, Vol 8, Iss 8, p 437 (2024)
Fatigue damage can occur in surface rock engineering due to various factors, including earthquakes, blasting, and impacts. The underlying cause for the variations in physical and mechanical properties of the rock resulting from impact loading is the
