What Is a Compression Tester?
A compression tester is a type of strength test for materials.
Also called a compression test, a compression tester applies a load to a specimen from above to determine its resistance to compressive forces.
In a compression tester, a load is applied to the specimen from above at a constant rate until the specimen fails or the load reaches a specified value, and the force and displacement applied to the specimen are measured.
This value is converted into a stress-strain diagram, and the maximum compressive stress obtained from the diagram is the compression strength of the specimen. The difference in stress between two specified points on the stress-strain diagram divided by the difference in strain is the compressive modulus.
