Brittle Creep Failure, Critical Behavior, and Time-to-Failure Prediction of Concrete under Uniaxial Compression

Figure 8

Log-log plots of axial strain rate against time for four specimens. The power-law fits (see the solid red lines in (a) and (b), and the solid blue lines in (c) and (d)) to the experimental data near failure are indicated in the figures. The power-law exponent is equal to and it is approximately equal to the theoretical value of −1/2 quoted in [31].
