6 FAQs about [Storage modulus of aluminum]

Does aluminum alloy have a loss modulus compared to elastic modulus?

It is observed that the due to a lack of viscoelasticity in aluminum alloy, the storage modulus is nearly the same as the elastic modulus. It is also observed in that the loss modulus is negligible compared to the storage modulus.

How does a low temperature alloy affect storage modulus?

The alloy shows a similar behavior at low temperature but the decrease in storage modulus increases sharply over 375 °C. The loss modulus is very small for the tested materials because of lack of viscoelasticity in metallic materials.

What is a storage modulus?

The storage modulus is closely related to material stiffness, which is often expressed as dynamic Young’s modulus. Thus, the storage modulus determines the stiffness of the material. It is also related to energy storage of a material upon application of a load.

What is the loss modulus of A356 alloy?

The value of the loss modulus for the A356 alloy is only 1.4% compared to the storage modulus at 50 °C. The damping parameter tanδ is also negligible at 50 °C. As the temperature is increased, the stiffness of the material decreases, which is reflected as the reduced storage modulus. Correspondingly, the loss modulus increases.

What is the difference between loss modulus and storage modulus?

It is also observed in that the loss modulus is negligible compared to the storage modulus. The value of the loss modulus for the A356 alloy is only 1.4% compared to the storage modulus at 50 °C. The damping parameter tanδ is also negligible at 50 °C.

How does frequency affect storage modulus?

Thus, the decrease in the storage modulus with frequency is larger at low frequency compared to higher frequencies, being independent of material type. More specifically, the decrease in the storage modulus of FGMs at 1 Hz as the temperature increased from RT to 400°C is 45 GPa. On the other hand, the decrease at 30 Hz is 35 GPa.
