4.9: Modulus, Temperature, Time

4.9: Modulus, Temperature, Time. The storage modulus measures the resistance to deformation in an elastic solid. It''s related to the proportionality constant between stress and strain in Hooke''s Law, which states that extension increases with force. In the dynamic mechanical analysis, we look at the stress (σ), which is the force per cross ...

5.4: Linear Viscoelasticity

The concept of "modulus" – the ratio of stress to strain – must be broadened to account for this more complicated behavior. Equation 5.4.22 can be solved for the stress σ(t) once the strain ϵ(t) is specified, or for the strain if the stress is specified. Two examples will illustrate this process: Example 5.4.2.

Interlocked CNT networks with high damping and storage modulus

The interlocked carbon nanotube (CNT) networks formed by floating catalyst chemical vapor deposition method is found to show greatly enhanced damping ratio (0.37–0.42) and much higher storage modulus (>11.0 GPa) compared to most of engineering damping materials and any other kinds of CNT networks and composites …
