The phrase "a closed form model" is correct and usable in written English.
It can be used in contexts related to mathematics, statistics, or modeling where a solution is expressed in a finite number of operations or a specific formula.
Example: "In our analysis, we utilized a closed form model to predict the outcomes based on the available data."
Alternatives: "a definitive model" or "a fixed form model".
A closed form model predicting debond growth in composite flanged joints is presented.
A closed form model of the EM reflection and absorption provides a tool for the optimization of the hybrid.
Highly nonlinear deflection versus temperature curves were predicted by a closed form model and match well with experimental measurements.
We give a closed form model for the mean and standard deviation of range readings from a rough brick wall as a function of normal distance and beam incidence angle.
Though computational and empirical models provide information concerning plate penetration, a theoretical, late time model provides the convenience and efficiency (computation of the full time history of the impact process is not necessary) of a closed form model with the rational basis of a physics based mathematical relationship.
This work presents a closed-form model of piezoresistive sensitivity for micromachined cantilevers working in longitudinal deformation mode.
Based on the closed form model which is briefly presented in "A complex model of underwater snake robots", empirical rules are derived in [46] through an extensive simulation study for the relationships between the parameters of the gait patterns, the consumed energy and the forward velocity for different motion patterns for underwater snake robots.
However, the computational burden and complexity increase dramatically compared to the closed form model of Kim et al. (2008), though on a modern computer these calculations still remain very reasonable.
The resulting closed form model is well suited for model-based control design schemes and stability analysis.
For the woven glass/epoxy joints analyzed, it was found that the closed form model predicted the peak values of G to within 20% of the FEA calculated values when the applied far-field strain εo was greater than 1.3 times the strain at which the flange first buckles, i.e., the critical buckling strain εcr.
A design method is proposed using closed form models derived from both microwave theory, and finite-element simulation.
