Abstract:

The novel method of detection and classification of the developing microfissures in an elastic environments is proposed. A probability model of the microfissures development is assigned that depends on time and space. The problem is reduced to the solution of the equation of elasticity with the limit and primary condition assigned by it. The rule of the development of the fissures' radius as discrete in time and space or as a random process is assigned. Two variants of the given problem are analyzed: Voltaire's equation or the ordinary differential equation with variable coefficients. The numerical results are given. A six-component vector-phase receiver settled on the unrestricted boundary is used as a receiver. The projection of the vectors of tension and shift are measured and calculated: their mutual correlation is possible. As a result, information about the intensity vector is provided that determines the coordinates and the intensity of the acoustic emission.
