Compression testing is key in materials science for evaluating how materials respond to compressive loads. It helps determine mechanical properties like stiffness, strength, and fatigue life. This overview covers the testing process, material properties, standards, applications, challenges, and best practices.

Dynamic mechanical analysis was first developed in the early to mid-1900s for determining the viscoelastic properties of plastics over a range of temperatures and test rates.

Since 1850 we have known that metal subjected to fluctuating stresses will fail at a stress much lower than required to cause fracture on a single quasi static pull to break.
