Detects small angular changes in the slope surface or retaining walls. Extensometers: Measures displacement along cracks or tension zones. Inclinometers:

displacements used to build the stress-strain curve can be determined by extensometers, InSAR or levelling. Laboratory consolidation tests yield measurements

Longitudinal and/or transverse strain is recorded using mechanical or optical extensometers. Indentation hardness correlates roughly linearly with tensile strength
