pdhonline.comUniaxial Compression Test AASHTO ASTM -D 2938 Purpose To determine the uniaxial compressive strength of rock (qu = F u = F C). Procedure In this test, cylindrical rock specimens are tested in compression without lateral confinement. The test procedure is simila r to the unconfined compression test for soils and concrete.

ceae.colorado.edu2.1 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). Pa rt OA represents the closing of existing cracks in the rock and an overall readjustment of the rock testing machine setup whereas part AB represents the elastic rock response.
Stress – Strain Relationships
wp.optics.arizona.eduspecimen subjected to a uniaxial load, we can write σ = Eε This relationship is known as Hooke’s Law and was first recorded by Robert Hooke, an English mathematician, in 1678. Note: Hooke’s Law describes only the initial linear portion of the stress-strain curve for a bar subjected to uniaxial extension.

The parameters, which are used to describe the stress-strain curve of a metal, are the tensile strength, yield strength or yield point, percent elongation, and reduction of area. The first two are strength parameters; the last two indicate ductility.

people.eng.unimelb.edu.auFor the uniaxial or unconfined compressive strength test a right circular cylinder of the material is compressed between the platens of a testing machine as illustrated in Fig. 8.1. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area.
