Reconstruction of the dynamics of a complex system by the time sequence of the release of elastic energy during deformation and destruction of wood and wood-based materials

The non-linear nature of the deformation of wood and wood composites under the influence of an external thermal-moisture-strength load on it requires, in its study, to consider this system as complexity. The analysis shows a certain determinism in the process of deformation-destruction: the system that generates such a release of elastic energy is not random and is controlled by a small number of determining variables. To describe a dynamic system in our case, it is sufficient to identify three variables whose variation in time will adequately describe the process of deformationdestruction. The time sequence analysis technique developed in the theory of dynamical systems makes it possible to distinguish between random and deterministic chaotic systems and to assess the complexity of these systems.
