Abstract
Dynamic and quasi-static tests for uniaxial compression of cylinders made of quartzite were carried out. The failure of the specimens was accompanied by fractoluminescence. The fractoluminescence was recorded by a photomultiplier tube (PMT) and a high-speed camera. The high-speed camera allowed us to visualize fracture process accompanied with fractoluminescence and PMT provided high temporal resolution for statistical analysis of fracture. A statistical analysis of the mass distribution of quartzite fragments and a statistical analysis of the time intervals between pulses on the signals from the PMT are carried out. The cumulative fragments mass distributions for all samples had two slopes, which were described by power functions. The cumulative time distribution between pulses was also described by a power function, which corresponds to brittle fracture of the material.
