Uniaxial compression test: how long can a rock resist? The Uniaxial Compression Test, or also uniaxial test or simply uniaxial test, is a test that allows to characterize the strength of a rock and is standardized according to the ASTM-D7012 standard.

The uniaxial compression test is the natural complement to the tension test, frequently producing larger strains without specimen failure. Compression tests, when used in conjunction with tension tests, are useful to determine if a material exhibits asymmetry in tension versus compression.

2.1 Uniaxial Compression Recall the typical stress strain response curve for a specimen of intact rock under uniaxial compression (see Figure 1 in Lecture Notes 5).

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.

In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression). It is opposed to tensile strength which withstands loads tending to elongate, resisting tension (being pulled apart).

May 23, 2024 · The uniaxial compressive strength (UCS) of rocks is a vital geomechanical parameter widely used for rock mass classification, stability analysis, and engineering design in rock engineering. Various UCS testing methods and apparatuses have been proposed over the past few decades.

Jul 2, 2024 · What is an unconfined compression test? The unconfined compression test, also known as the uniaxial compressive strength test, assesses the unconfined compressive strength (UCS) of a concrete, cement, sand, clay, or soil sample under axial compressive loading.

Dec 10, 2024 · This study aimed to investigate the uniaxial compression behavior of UHPC reinforced with BFRP minibars and gain the stress–strain relationship under uniaxial compression to support the structural design of the novel UHPC structures.

Jul 5, 2023 · In this paper, the typical uniaxial compression test of a cylindrical specimen has been modeled using the finite element method. Ideal cases for compression testing have been developed using only the specimen model under load and displacement-controlled test conditions.

Jul 12, 2024 · Reasons are given against the existence of a uniaxial compressive strength failure for concrete, and a piece of evidence in this direction is provided by concrete specimens subjected to pure hydrostatic compression, that do not fail at all.
