Influence of weak electric field on spatial-temporal dynamics of damage evolution during granite deformation

The influence of the weak electric field on a process of damage accumulation and main crack formation is investigated on a base of the acoustic emission data obtained during a uniaxial quasistatic compression of granite samples. It is shown that continuous external impact leads to a change in deformation and fracture processes. This, in turn, leads to a change of acoustic emission parameters and stages of acoustic emission.
