PHYSICAL FUNDAMENTALS OF MESOMECHANICS OF PLASTIC DEFORMATION AND FRACTURE OF SOLIDS
固体范性形变与断裂的介观力学物理原理

The research review on plastic deformation and fracture of solids based on phvsicalmesomechanics is presented. A solid under loading is considered in physicalmesomechanics as multilevel self-consistent system. where the plastic flows atmicro-meso- and macrolevels are natrually interrelated according to the principle ofscaIe invarlance.Bulk mesovolumes are moved at the mesoscale level according toscheme "shear rotation". Plastic deformation and fracture of solids are considered astwo stages of the same process.
