FIGURE 7. Mechanical property correlations to steady state signals across specimens.
Linear correlations to peak stress are shown for proton concentrations derived from BEuTE (short/long-T2*) and CuTE methods (A, left) as well as for concentrations derived from the proposed AIR/DAFP methods (A, right). Pearson’s r2s for correlations between the different methods’ water concentrations and various mechanical properties are summarized in B. While AIR and DAFP were good correlates to mechanical properties, none of the FID methods exhibit statistically significant correlations (p < 0.05) for any of the mechanical properties surveyed.
