Compressive Properties and Testing Methods

Compression testing is a key mechanical test to assess material behavior under crushing loads. It is crucial for ensuring the integrity and safety of materials like concrete and foam, used in various industries. The tests are performed on universal or dynamic fatigue testing machines and are vital in manufacturing processes, especially for consumer electronics and medical devices. Compression testing helps determine properties such as yield strength and compressive strength, ensuring products meet safety standards.
