This approach, which has been tested on isotropic plates, allows to develop theoretical and experimental methods for determining the trajectories of the vertices of the cracks and the speed of their propagation in anisotropic plates. The developed method of determining the stress state of plates with cracks, taking into account the contact of their faces, allows us to extend the application of the developed methods to calculation of fracture processes in compression zones.
