Inertial effects of quartz force transducers embedded in a split Hopkinson pressure bar

Dynamic Separation of Resistance Spot Welded Joints: Part I—Experiments

“…Furthermore, at a given frequency, the error is larger for specimens with less stiffness. Compensation for acceleration in an impact test using a split Hopkinson pressure bar was developed using quartz force transducers attached to the bar [20]. It shows that the high initial bump in the recorded stress is due to the inertia effect and can be eliminated with proper correction.…”

Dynamic mechanical response of bovine gray matter and white matter brain tissues under compression

“…In order to increase the transmission signal, a hollow aluminum transmission bar was used (Chen et al, 1998) and highly sensitive semiconductor strain gages (Kyowa Electronic Instruments Co, LTD, KSP-2-1K-E4) were attached on the transmission bar. Quartz-crystal force transducers (Boston Piezo-Optics, Inc.) were used to verify the dynamic equilibrium in the specimen (Chen et al, 2000;Casem et al, 2005).…”

Celebrating 75 Years of the Society for Experimental Mechanics and the Study of Dynamic Behavior of Materials

“…Building on the society's history in photoelastic coatings and full field methods there have been expansive studies into dynamic fracture mechanics, such as [19][20][21][22][23][24][25]. SEM members have contributed significantly to advances in the Split Hopkinson Pressure Bar (SHPB) or Kolsky Bar technique [6], expanding it's loading range, analysis, and material applicability [25][26][27][28][29][30], methods have been developed for heating specimens [31], and moving from strain gages to embedded quartz force transducers [32,33]. The SHPB has been expanded into tensile loading [34][35][36][37] including 3D full field strain measurements [38], shear loading through both torsion bars [39] and specimen design [40], fracture [41], and dynamic friction measurements [42].…”
