I have performed some high strain rate split hopkinson
compression tests. The oscilloscope reads the incident and reflected
displacments (in input pressure bar) and transmitted displacment (in output
pressure bar) in volt. To convert displacement in volt (output voltage) to
mechanical strain (m/m), I have a difficalty. What is the relationship between
the output voltage (volt) (the reading from oscilloscope), excitation voltage (volt)
and strain gauge Gauge Factor (GF)?
