As noted for the specimens connected to a rigid base, signal
from the pressure transducer is distorted by high-frequency oscillations,
and so further analysis will be focused on the strain gauge
histories. Fig. 8-right shows the pressure histories from two strain
gauges, 25 mm (SG2) and 50 mm (SG1) from the base. There is not
only a resemblance in the pattern of the traces, but also in the
