Napomena
A full-scale 3D analysis of a Split Hopkinson Pressure Bar experiment on granite material using a 3D combined Finite-Discrete Element Method (FDEM) is shown. Previous efforts to simulate Split Hopkinson Pressure Bar experiments using the 2D FDEM had obtained a very good match for the loading portion of the experiment. This work extends those efforts by modeling the entire 3D Split Hopkinson Pressure Bar experimental setup, and reproducing the softening behavior of the sample after breakage. This modeling effort introduces the effect of a compliant interface between the bars and the sample.
