Method to Address Brittle Rock Strength Scatter Through Fracture Density

Introduction
Rock strength is an important criterion for the classification of rocks to optimize construction usage and surface or subsurface structure designs (Yilmaz 2009). Strength criteria include peak strength criteria, residual strength criteria, and yield strength criteria. The criteria are usually mathematical relations between various stress or strain components that belong to one point in the stress or strain field. However, the relation could be confused by many factors, which often make it inconceivable. These factors can be divided into three groups: (1) composition of the specimen, such as mineral composition, and arrangement of the mineral grains and cracks (Hattiangadi and Bandyopadhyay 2000) and formation conditions (Rajabzadeh et al. 2012); (2) geometrical conditions, such as size (Darlington et al. 2011) and shape (Malaikah 2005; del Viso et al. 2008); (3) external damage conditions, such as load path (Yang et al. 2011; Erarslan and Williams 2012), load rate...
