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

Figure 3

Dynamic rupture in concrete (samples are labeled as MS1, MS2, MS3, and MS4) under monotonic loading at a constant displacement rate (0.05 mm/min). The specimens fail suddenly in the postfailure stage after the peak force is reached. Concrete exhibits some scatter in the attained peak force and failure strain. In these monotonic tests, the displacements in the brittle creep tests are selected to be the same as those corresponding to the 80–90% peak forces.
