摘要
Some new notions of discrete fracture mechanics are introduced: fracture quantum, homogeneous and isotropic fracture quanta sets, and fracture quanta sets that are weakly sensitive to the boundary. Non-local functional strength conditions for a fracture quantum and for a body are considered. Definitions are given for strength homogeneity, isotropy, finite non-locality, and weak sensitivity to the boundary for a discretely fracturable body. Quantum-point dualism in a fracture description is analyzed, which allows one to go from the continuous point of view to the discrete one and vice versa. Presented approaches are applied to generalizations of some known non-local strength conditions on near-boundary points.
