Storage modulus (G'') and loss modulus (G") for beginners
In both cases the complex modulus would be higher, as a result of the greater elastic or viscous contributions. The contributions are not just straight addition, but vector contributions, the angle between the complex modulus and the storage modulus is known as the ''phase angle''.
Storage Modulus
The storage modulus indicates the solid-like properties of the plastic, whereas, the storage modulus indicates the liquid behavior of the plastic. If we consider the response of silly putty to …
