The shock experiment is processed on the Split-Hopkinson pressure bar（SHPB）in order to measure the matching error of the ytterbium stress sensors which are embeded in concrete sample.The experiments show that the matching coefficient of the sensor in concrete is stable and the experimental value is 1.017.The flatpacked sensor can efficiently reduce stirring to stress field of measured medium

the sensor can be widely applied to the shock stress measurement in concrete or rock under cartridge explosion and weapon penetration.
