Rock Fracture Mechanics and Fracture Criteria

This open access book delves into the realms of geotechnical engineering and solid mechanics. In order to establish fracture parameters that are both relevant and conducive to safety, the book extensively investigates the fracture mechanical properties of mode I, mode II, and mode III in brittle rock materials.

Strength of Fractured Rocks

, 2015
In this report we present a study on the strength of rocks which are partially fractured from before. We have considered a two dimensional case of a rock in the form of a lattice structure. The fiber bundle model is used for modelling the $2-D$ rock. Each lattice site is considered to be a fiber which has a breaking threshold.
