· 1. Rock Elasticity. 1. James A. Craig Omega 2011. 3. Ability of materials to resist and recover from deformations produced by forces. Applied stress leads to a strain, which is reversible when the stress is removed. The relationship between stress and strain is linear; only when changes in the forces are sufficiently small. Most rock mechanics ...
