Shear Strength Testing (Triaxial)


Shear Strength Testing (Triaxial)

Three main types of triacial testing (typically assumes isotropic materials):


- Unconsolidated Undrained (UU)

- Consolidated Undrained (CU)
Extension tests availble

-Consolidated Drained (CD)

Ultrasonic Velocity Testing

Ultrasonic Velocity Testing

- Ultrasonic Velocity Testing (ASTMD2845 or ISRM)

- Used extensively in Coal and Oil and Gas Industries (well bedded deposits with minimal micro-fracturing)

- Applied for isotropic rocks or rocks having slight anisotropy
