摘要：
A survey of the authors' papers dealing with the physical foundations of multilevel nonlinear fracture mechanics is presented. The gauge theory of defects is used to obtain wave equations that predict the possibility of a crack development as a nonlinear wave process. Under viscous fracture conditions, nonlinear fracture waves disperse forming local mesovortices in the form of dynamic rotations. Experimental data confirming the wave theory predictions are given. The fracture development is related to the structure-phase breakup of a deformable crystal in the regions of its strong curvature.
