incompressibility condition

incompressibility condition

[¦in·kəm‚pres·ə′bil·əd·ē kən‚dish·ən]
(fluid mechanics)
The condition prevailing when the time rate of change of the density of a fluid is zero; this is a valid assumption for most problems in dynamic oceanography.

p is a Lagrange multiplier associated to the global incompressibility condition, and g is the multiplier associated to the incompressibility of the elastic part.
The proposed damage model in crosslinked rubbers is based on two assumptions: (i) irreversibility of chain scission because of quick neutralization of free radicals formed in scission process (33), and (ii) incompressibility condition common in damage models, because the volume concentration of microscopic voids formed by the scissions is negligible almost until the failure.
I, is also known as the incompressibility condition or the divergence-free condition on the velocity field.
It should be mentioned that the incompressibility condition is attentively verified only in the filled part, although the same operation is performed in the void part to keep simplicity of the algorithm.
They are related to each other by the incompressibility condition of [[lambda].

The total energy functional of materials including the incompressibility condition can be expressed in terms of the invariants of the Cauchy-Green deformation tensor as [22]
The incompressibility condition is a consequence of the hypothesis that the potential energy of the entire network equals the sum of potential energies of individual chains.
The incompressibility condition is also fulfilled by these plasticized polyamides.
For incompressible fluids, the density is constant and the full density transport equation reduces to the incompressibility condition.
