多层次固体断裂非平衡统计理论框架

Theoretical Framework of a Multilevel Nonequilibrium Statistical Theory of Fracture for Solid Materials

从分析实际固体材料的微观细观缺陷结构出发，在断裂非平衡统计理论基础上，给出了微观细观宏观多层次结合的固体断裂非平衡统计理论框架图，描述了各层次在断裂过程中的相互联系，讨论了微裂纹、晶界和晶格原子结构及有关电子云分布等在断裂过程中的作用．

Starting from micro-and meso -structure of real solid materials, the theoretical framework scheme of micro-meso-macro multilevel nonequilibrium statishcal theory of fracture is given. The relationship among all the different levels in a fracture process is described. The roles of microcrack, grain boundary, crystal lattice and its electron cloud in the fracture process are discussed.
