Abstract:To study the effects that the perennial freeze–thaw environment exerts on the dynamic mechanical properties of marble, which characterizes the Qinghai-Tibet Plateau, impact tests were conducted, and saturated marble was utilized; thus, we analyzed the effect of different loading rates on its dynamic compressive strength, fragmentation pattern, and energy-absorbing density. The results indicate the following: (1) When 42.02s-1 ≤ε˙≤ 49.20s-1, the degree of fragmentation and the fractal dimension of saturated sta… Show more
