Ice783 (NG81): coarse ice I seed (sieve size 0.5 - 1 mm)

T = 240 K, P = 50 MPa, s = 8 MPa step (1)
T = 240 K, P = 50 MPa, s = 10 MPa (to avoid motor resonance) step (2)

 

Legend: Upper graph of each pair is motor speed V (proportional to edot); lower graph is load (in volts). Translate motor V to edot thus: V1.00 ≈ 6e-6/s ≈ 2%/hr. Load to stress translation for ice767 is roughly ____ MPa/mV, with a __ mV zero offset. Horizontal scale is time. 5000 ≈ 14 hrs.
e = 0.25
