description |
of underground cavities and field-leveling excavation. Dynamic mechanical performance of rocks
has been gradually attached importance both in China and abroad. Concrete and rock are two kinds of the most
frequently used engineering materials and also frequently used as experimental objects currently. To compare
dynamic mechanical performance of these two materials, this study performed dynamic compression test with
five different strain rates on concrete and rock using Split Hopkinson Pressure Bar (SHPB) to obtain basic
dynamic mechanical parameters of them and then summarized the relationship of dynamic compressive
strength, peak strain and strain rate of two materials. Moreover, specific energy absorption is introduced to
confirm dynamic damage mechanisms of concrete and rock materials. This work can not only help to improve
working efficiency to the largest extent but also ensure the smooth development of engineering, providing rich
theoretical guidance for development of related engineering in the future |
