SHPB Technique Used for Measuring Dynamic Properties of Material in High Temperature
|
Abstract:
Two schemes for high temperature SHPB experiment are discussed in this paper: heating only the specimen then quick targeting bars and heating both specimen and bars then eliminating the effects of temperature gradient in data-processing.The former avoids the heating of rods but the operation is complicated,the latter is simple and steady.For analyzing temperature gradient in latter scheme,a simplified model was designed and modified by numerical calculation,based on the precision appropriate assumption,whic...
