Abstract:

Solutions to the one-dimensional wave equation along with simple descriptions of the sample’s mechanical response are used to analyze a Kolsky bar experiment. If the approximate sample behavior is known, the experiment can be predicted in advance. This allows one to design the experiment (choice of bar and sample geometry, striker speed, instrumentation, etc.) to obtain the desired specimen deformation (rate, final strain, etc.). The effects of pulse shapers and tapered projectiles are included.
