| Abstract: | A SHPB apparatus was modified as a variable cross section SHPB.In order to determine the various parameters,stress wave propagation in a right cone variable cross section bar was studied numerically.Also,the effects of two end diameters,transition portion length and cone angle on wave propagation were discussed. |

| Keywords: | SHPB concrete cone bar stress wave |
