The Damage Mechanics of Brittle Solids in Compression
Abstract
The development of microcrack damage in brittle in solids in compression is analyzed, using a simple model. The model is developed from recent detailed analysis of the initiation, propagation and linkage of microfractures from pre-existing cracks, voids, or other in-homogeneities. It describes the evolution of damage with strain and from it the stress-strain response, and criteria for failure, can be established. The results are used to construct failure surfaces in stress space which combine information about brittle failure with data describing the onset of plastic yielding. Such failure surfaces are constructed for a number of rocks and are compared with previously published experimental data. Brittle failure, Damage mechanics, Microfractures, Compressive failure.
