Compression Testing
When the response of a material or product to being “pressed” or “pushed on” needs to be determined, compression tests are used.
About Compression Testing
Compression testing provides information on compression stress and compression strain as a sample is pushed and pressed at various loads.

Approaches
Compression testing can be used to determine mechanical property degradation as a result of product use, accelerated aging, or response to chemical exposure.
Mechanical strength data for research and development and quality control can be aquired through compression testing.
We can also create custom, and validated, compression tests or cyclic loading in compression can be accomplished to characterize a product in a simulated application environment. For example, we did this to test bioabsorbable screws under cyclic compression loads at elevated temperature in saline.

Sample Considerations
Plastic and rubbery materials can be analyzed with compression testing, as well as actual products. We can also use compression testing to analyze metals.
