Experimental Studies on Compressive Behaviour of Granite Using Quasi-Static and Split Hopkinson Pressure-Bar Test.

Abstract

The mechanical characteristics of the materials will change because of the shift in strain rates. This study employs several compressive experiments to investigate the static and dynamic behaviour of the granite specimen at various strain rates. The results of the experiment showed that the granite's mechanical properties and fracture behaviour had changed dramatically. However, the findings of compressive behaviour in the SHPB test revealed more micro-cracks as the strain rates increased. Additionally, the phase pattern of a granite specimen captured using a scanning electron microscope (SEM) shows intergranular fractures, and the grain-scale river pattern is observed in the data.
