Introduction to Dynamic Mechanical Analysis and its
If storage modulus is greater than the loss modulus, then the material can be regarded as mainly elastic. Conversely, if loss modulus is greater than storage modulus, then the material is predominantly viscous (it will dissipate more energy than it can store, like a flowing liquid). Since any polymeric material will exhibit both storage and

6 FAQs about [Sbsdma storage modulus]
What is the difference between storage modulus and dynamic loss modulus?
The storage modulus is often times associated with “stiffness” of a material and is related to the Young’s modulus, E. The dynamic loss modulus is often associated with “internal friction” and is sensitive to different kinds of molecular motions, relaxation processes, transitions, morphology and other structural heterogeneities.
What are storage and loss modulus in amplitude sweep?

What is a storage modulus master curve?
In particular, the storage modulus master curve presents only one smooth step transition, corresponding to one peak in the loss modulus frequency spectrum, and the behaviour is asymptotic when going to either zero or infinity frequency.
What is the ratio of loss modulus to storage modulus?
The ratio of the loss modulus to the storage modulus is defined as the damping factor or loss factor and denoted as tan δ. Tan δ indicates the relative degree of energy dissipation or damping of the material.
