What is a uniaxial compressive strength?

Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.

What is UCS concrete?

Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the Unconfined Compression Test is also known as Uniaxial Compression Test.

What is the difference between uniaxial compressive strength and unconfined compressive strength?

Answer: Uniaxial compressive strength is the ultimate compressive stress of the rock specimen failure under uniaxial compression conditions. Unconfined compressive strength means that the strength of a rock or soil sample when crushed in one direction in a triaxial test without any lateral restraint.

What is UCT test?

Unconfined Compression Test (UCT) is one of the tests to determine strength and stiffness parameters of soil. Despite of its limitation compared to triaxial test and direct shear, it is used widely due to its simplicity.

What is uniaxial test?

Uniaxial testing is a test in which a sample is subjected to a uniaxial force until failure. The uniaxial force can be applied as either a tension or a compression. During these tests, the forceapplied to the specimen is recorded as a function of displacement between the grips of the testing machine.

What is unconfined compression?

Unconfined Compression Test (UCT) is a simple laboratory testing method to assess the mechanical properties of rocks and fine-grained soils. It provides a measures of the undrained strength and the stress-strain characteristics of the rock or soil.

What is uniaxial testing?

What is uniaxial compression?

A measure of a material’s strength. The uniaxial compressive strength (UCS) is the maximum axial compressive stress that a right-cylindrical sample of material can withstand before failing. It is also known as the unconfined compressive strength of a material because confining stress is set to zero.

What is UCS soil?

Unconfined Compressive Strength (UCS) stands for the maximum axial compressive stress that a cohesive soil specimen can bear under zero confining stress. Unconfined compression test is one of the fastest and cheapest methods of measuring shear strength of soil.

What is uniaxial force?

A uniaxial stress or force acts in one direction only. Metals are tested under uniaxial stress. When a specimen is subjected to a uniaxial loading (along its primary axis) the force acting over the cross-sectional area generates a tensile stress and strain within the material.

What is uniaxial material?

Uniaxial crystals are transmissive optical elements in which the refractive index of one crystal axis is different from the other two crystal axes (i.e. ni ≠ nj = nk). This unique axis is called the extraordinary axis and is also referred to as the optic axis.
