This work presents a decision-tree-based Fuzzy Inference System (FIS) for making optimal choices in the development of reduced-order finite element (FE) models, in our case, shell-solid multifidelity models. FE analysis is widely used to simulate the

Design of modern control laws motivates the creation of state-space models from aeroservoelastic models. Balanced truncation is often used to create reduced-order models. In the present work, a reduced-order model that employs a change in time scale

The Simplified Potential Energy Clock Model has been previously shown to predict accurately glassy polymer responses such as yield, creep, enthalpy relaxation, and physical aging. It was now used to predict the behavior of monofilament Nylon fiber. E

Computational micromechanical analysis of high-stiffness hollow fiber nanocomposites is performed using the finite element method. The high-stiffness hollow fibers are modeled either directly as isotropic hollow tubes or equivalent transversely isotr

In this paper, computable global bounds on errors due to the use of various mathematical models of physical phenomena are derived. The procedure involves identifying a so-called fine model among a class of models of certain events and then using that

A flexible material, such as a woven or braided fabric, may be tailored to form an arch when inflated. Such arches have been used as the framework for transportable shelters and are analyzed in this paper. It is assumed that the cross section of the

To accurately model the structural response of e ber-reinforced polymer-matrix composites, it is necessary to account for viscoelastic behavior of the polymer matrix. Therefore, the geometrically linear dynamic analysis capability of a recently devel
