Cho et al. ◀ Strength-reducing mechanisms in mantle rock during the Flood ▶ 2018 ICC 715 Figure 5 . Plot for the initial viscosity profile throughout the mantle’s depth in TERRA. The reference viscosity η 0 is 23 in base 10 log scale. Based on Eq. (19), the pressure and temperature dependent initial viscosity profile was generated before the simulation starts. Figure 4. Plot for experimental stress-strain curves (marks) of olivine and their calibrated results (solid lines) at various temperatures, pressures, strain rates, and stress states, using the ISV model constants (summarized in Table 1). The error bars show the uncertainty of each experimental datum. The ISV model fits most of the experimental data within its uncertainty range. In the legend, C and S represent uniaxial compression and shear (torsion) deformation, respectively. The next numbers with ‘GPa’ and ‘K’ indicate the pressure and temperature in each experiment, respectively. The next number with ‘s -1 ’ indicates the applied strain rate. Using this calibrated ISV model for olivine, TERRA calculates realistic mechanical properties at various temperatures, pressures, strain rates, and stress states.
