Rock Mechanical Properties and In Situ Stresses
Abstract
This chapter opens with basic definitions of Young’s modulus, Poisson’s ratio, fracture toughness, and brittleness and fracability ratios. Next, vertical and minimum and maximum horizontal stress, and Biot’s coefficient are explained. This chapter continues with various states of stress and ends with detailed discussions on transverse and longitudinal fractures. Different examples in each subsection on calculating the rock mechanical properties and in situ stresses are provided.
