Rock Strength - an overview | ScienceDirect Topics
Rock strength and porosity have good correlations for various rocks, and porosity can be obtained from lab tests or from density and sonic logs. In the following equations, the rock strength UCS is in MPa and porosity is in percent (%). For shales in the North Sea (geologically young and weak shales, mostly high-porosity Tertiary shales), Horsrud (2001) proposed the following correlations for

Rock - Stress-strain relationships | Britannica
Rock - Rock - Stress-strain relationships: The deformation of materials is characterized by stress-strain relations. For elastic-behaviour materials, the strain is proportional to the load (i.e., the applied stress). The strain is immediate with stress and is reversible (recoverable) up to the yield point stress, beyond which permanent strain results.
