What is Compression Testing and How to Apply?

A compression test is any test in which a material encounters opposing forces that push the sample in from opposite sides or otherwise compress, crush, or flatten. The test specimen is usually placed between two compression plates, which distributes the applied load over the entire surface area of the two opposing faces of the test specimen, and then the plates are pushed by a universal testing machine which causes the specimen to flatten. A compressed specimen is generally shortened in the direction of the applied forces and expanded in the direction perpendicular to the force. The compression test is essentially the opposite of tensile test.

 

How is the Compression Test Performed?

A compression fixture suitable for the specimen is connected to a test device. The specimen is then placed in the fixture. The machine applies the required amount of load to the specimen and the specimen is crushed.

 

What is the Purpose of the Compression Test?

The purpose of compression testing is to determine the behavior or response of a material when experiencing a compression load by measuring key variables such as strain, stress, and deformation. Compressive strength, yield strength, ultimate strength, elastic limit and modulus of elasticity can be determined, among other parameters while a material is tested with compression testing. After these measurements are made, it can be understood whether the material is suitable for certain applications.

 

 The most common materials to which the compression test is applied are materials with high compressive strength such as composites, concrete, wood, stone, brick, mortars, polymers, plastics, foam and metals.
