On compression, the specimen will shorten. The material will tend to spread in the lateral direction and hence increase the cross-sectional area. In a compression test, the specimen is clamped at the edges. For this reason, a frictional force arises which will .Triaxial Testing Soil triaxial testing is a fundamental procedure in geotechnical engineering, used to determine a sample’s shear strength parameters. . An additional test that can be conducted with the triaxial apparatus is the unconfined compression test, which involves shearing the specimen with no confining pressure.
2 Compression Test. A compression test is conducted in a manner similar to a tensile test except that the force is compressive and the specimen contracts along the direction of stress. Equations (1) and (2) are used to compute compressive stress and strain, respectively. By convention, a compressive force is taken to be negative, which yields a .

Definition. Compression is the process of reducing the volume or size of an object or material by applying force or pressure. It involves the act of compressing, squeezing, or pressing something together, resulting in a decrease in its overall dimensions or density. . 5 Must Know Facts For Your Next Test. Compression is a key concept in the .Tensile Stress. Tensile stress is that type of stress in which the two sections of material on either side of a stress plane tend to pull apart or elongate as illustrated in Figure 1(a).. Compressive Stress. Compressive stress is the reverse of tensile stress. Adjacent parts of the material tend to press against each other through a typical stress plane as illustrated in Figure 1(b).
When the stress σe is plotted against the strain \(\epsilon_e\), an engineering stress-strain curve such as that shown in Figure 2 is obtained. Figure 1: The tension test.
