The compression test is a procedure that tests a number of a material’s compressive strength, as well as other properties such as yield strength, ultimate strength, elastic limit, and elastic modulus. To perform this test, the material is subjected to compressive forces that push inward into the material. This force aims to crush, flatten, or squash the material. To perform this test, the material is placed in between 2 plates. The plates then apply increasing force into the material, which aims to flatten the object. The compression test is technically the opposite of the tension test. Because of the compression forces, the object gets shortened on the direction of the forced and stretched at the direction perpendicular to the force.
