Ice778: Nebulized f.g ice; with hydrostatic chamber

T= 200 K, 100 MPa, 3.3 hrs step (0) hydrostatic compaction
T = 220 K, P = 50 MPa, s = 2->2.4 MPa step (1)
T = 220 K, P = 50 MPa, s = 2.4 MPa step (2)
T = 220 K, P = 50 MPa, s = 3.4 MPa step (3)
   

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 ice ___is roughly ___ MPa/mV, with a __mV zero offset. Horizontal scale is time. 5000 ≈ 14 hrs.
