The critical tensile stress at which a rock fails is called as the tensile strength of the rock.
The tensile strength can be utilized as a strength parameter to characterize the rock. It also helps in the design of hydraulic fracturing.
The tensile strength usually correlates well with other mechanical properties such as unconfined compressive strength (UCS) and fracture toughness (KIC).
Our Brazilian tensile test (Indirect Tensile strength test) clamps are made from stainless steel and are custom‐machined clamps for standard sample sizes of up to 2 inches in diameter.
We can also design and fabricate custom pieces as per customer specification. External LVDTs can be mounted on the sides of the clamp to measure axial strain in addition to load cell readings. The high precision machining allows for accurate piston alignment.
