Deformation and strength of rock are known to be functions of confining pressure. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which .
Significance — The data obtained from a compression test may include the yield strength, the yield point, Young's modulus, the stress-strain curve, and the compressive strength (see Terminology E6).In the case of a material that does not fail in compression by a shattering fracture, compressive strength is a value that is dependent on total strain and specimen . De ection A compression test in which the force required to cause a speciÞed deßection is determined. 3.1.2 Test Method B Compression Test at Speci ed Force A compression test in which the speciÞed mass or compressive force is placed on the specimen and the resulting deßection is measured and recorded. 4. Signi cance and Use 4.1 These test . 5.1 This test method is designed to produce compressive property data for material specifications, research and development, quality assurance, and structural design and analysis. When tabbed (Procedure B) specimens, typically unidirectional composites, are tested, the CLC test method (combined shear end loading) has similarities to Test Methods .
4.1 This test method provides information regarding the behavior of cellular materials under compressive loads. Test data is obtained, and from a complete load-deformation curve it is possible to compute the compressive stress at any load (such as compressive stress at proportional-limit load or compressive strength at maximum load) and to compute the effective .the others, produces compression set, its effects as a whole are simulated more closely by compression flexing or hysteresis tests. Therefore, compression set tests are considered to be mainly applicable to service conditions involving static stresses. Tests are frequently conducted at elevated tempera-tures. 5. Test Specimens

This shear strength may be applied to field conditions where full drainage can occur (drained conditions) or where pore pressures induced by loading can be estimated, and the field stress conditions are similar to those in the .
This close-up of the test in previous slide shows the 5,300 kN(1,200 k) capacity hydraulic jack being used to generate the test load. The jack reacts against the beam above, which loads the test pile in compression and the reaction piles in tension. The load is being measured using a load cell (note data cable) and theASTM D575 is a testing standard used to determine the stiffness of rubber materials in compression. ASTM D575 allows rubber suppliers to characterize the stiffness of the material they produce to help downstream manufacturers .2.1 ASTM Standards: D 695 Test Method for Compressive Properties of Rigid Plastics2 D 792 Test Methods for Density and Specific Gravity (Rela-tive Density) of Plastics by Displacement2 D 883 Terminology Relating to Plastics2 D 2584 Test Method for Ignition Loss of Cured Reinforced Resins3 D 2734 Test Methods for Void Content of Reinforced Plas .Test Methods D 790. 4.
