energy storage stiffness and energy dissipation stiffness

What is stiffness associated with energy storage?

Stiffness associated with energy storage represents only one aspect of the viscoelastic properties of substrate matrices. Another crucial aspect pertains to energy dissipation and the rate at which it occurs.

Why is the stiffness of a viscoelastic system constant?

The stiffness of these viscoelastic systems is not constant; rather, it is influenced by the interplay between energy storage, which tends to increase stiffness, and energy dissipation, which tends to reduce it. These processes can occur simultaneously or at different rates.

What happens when energy dissipation exceeds energy storage?

When the energy stored exceeds the energy dissipated, the system exhibits characteristics typical of a viscoelastic solid. Conversely, when energy dissipation surpasses energy storage, the system behaves as a viscoelastic liquid. The storage contributes to the stiffening of a soft-matter system, whereas energy dissipation leads to its softening.

How does the stiffness of a system change over time?

The stiffness of a system is influenced by the interplay between elastic energy storage, which contributes to system stiffening, and energy dissipation, which leads to system softening. As a result, the stiffness of the system varies over time.

Why is energy storage correlated with matrix stiffness?

Energy storage is directly correlated with the matrix residual stress and consequently with the matrix stiffness . Extension leads to short-term energy dissipation caused by disruption of inter-chain bonds, while the effective radii of domains increase.

How does energy dissipation affect cellular stiffness?

The accumulation of energy causes the reinforcement of cell-cell and cell-matrix adhesions, which lead to stiffening of contractile multicellular systems, whereas energy dissipation contributes to their softening [19–21]. The overall stiffness of the system is thus a manifestation of a competition between these two opposing effects.

The stiffness of a system is influenced by the interplay between elastic energy storage, which contributes to system stiffening, and energy dissipation, which leads to system softening.
