Synergetic principles of physical mesomechanics

A synergetic methodology of physical mesomechanics is developed. Fundamental principles underlying the approach are discussed and formulated. The methodology is shown to account for and substantiate well-known plastic-deformation and fracture mechanisms in solids under various loading conditions. An analysis of the available experimental evidence suggests that the key meso- and macroscale processes developed in solids under load occur at maximum tangential stresses. Microscale deformation caused by dislocations is self-adaptable. Physical mesomechanics establishes natural relations between the physics of dislocation-induced deformation, continuum mechanics of solids, and fracture mechanics.
