Abstract
In focus are methodology and effect of micro- and nano-indentation method in studying local deformation and failure of rocks. By micro- and nano-indentation, numerical values of Young’s modulus, and hardness of rocks and minerals have been obtained. The values of fracture toughness are obtained for separate minerals and at grain boundary. The authors highlight the use perspectiveness of the described method in estimating strength and deformation characteristics of rocks.
