Table 2. Young’s Moduli E Calculated from Longitudinal Sound Velocity Assuming a Poisson’s Ratio of ν = 0.2 ± 0.05a.
ρ [g/cm3] | E [MPa] | |
---|---|---|
reference | 0.411 ± 0.007 | 627 ± 62 |
sheared ∥ | 0.409 ± 0.032 | 627 ± 98 |
sheared ⊥ | 0.409 ± 0.032 | 335 ± 68 |
In the case of the sheared sample, ∥ denotes the mechanical properties along the axial direction of the cylindrical monolith and ⊥ along its radial direction.
