Storage modulus determination method

Dynamic Mechanical Analysis (DMA) determines elastic modulus (or storage modulus, G'), viscous modulus (or loss modulus, G'') and damping coefficient (Tan D) as a function of temperature, frequency or time. Scope: Examples of standards: ASTM D4065, D4440, D5279 [pdf]

Metal storage modulus value

The storage modulus is calculated using rheometer data analysis and provides a measure of the material's ability to absorb energy and molecular relaxation as a function of temperature. [pdf]
