The phrase "as an internal variable" is correct and usable in written English.
It can be used in contexts related to programming, mathematics, or any field where variables are discussed, particularly when referring to a variable that is used within a specific scope or function.
Example: "In this function, we will define the value as an internal variable to ensure it is only accessible within the function's scope."
Alternatives: "as a local variable" or "as a private variable".
It is based on the evolution of dislocation density treated as an internal variable.
For the spatial discretization, a finite element strategy is applied which introduces the current individual cell orientation as an internal variable on the integration point level.
The key feature of the new proposal is that the term of strain gradient plasticity is represented as an internal variable to increase the tangent modulus.
Motivated by microscopic observations, a grain rotation based geometric softening mechanism is implemented as an internal variable within a viscoplastic constitutive setting.
The degree of monomer conversion is used as an internal variable that dictates the mechanical properties of the cured polymer at different curing states, including volume shrinkage, glass transition temperature, and nonlinear viscoelastic properties.
To solve the resulted equation in time domain, both explicit and implicit integration algorithms are developed, where the growth tensor is updated as an internal variable of Gauss point.
Parameter ζ≤0 is not an internal variable.
Considering the "time of contamination" of particles as a new internal variable is thus made necessary.
A response at the idler frequency need not be induced at the input, nor measured as an output variable, for it to play an important role as an internal state variable.
The MD results were then inserted into a new hydrogen associated void nucleation model that operates as an internal state variable in the context of continuum thermodynamic plasticity.
Averaged dislocation density is assigned as an internal state variable to address the microstructural slip, which is the critical mechanism in inelastic deformation of polycrystalline metals and alloys.
