Dynamic Mechanical Behavior of Sandstone under Static-Dynamic Combined Cyclic Impact

Abstract

Abstract This study investigates the dynamic mechanical behavior of sandstone under combined static and dynamic cyclic impact loading. For this purpose, a 100-mm-diameter split Hopkinson pressure bar is employed to conduct cyclic impact tests on ... Graphical Abstract The Graphical Abstract consists of three sections. The upper portion of the first section illustrates the drilling and blasting excavation of a rock tunnel, while the lower portion depicts the rock subjected to coupled static–dynamic ...
