Hierarchical Adaptive Modeling

Abstract

Computational procedures are developed for evaluating the hierarchical sensitivity coefficients of the nonlinear response of composite and sandwich structures. The hierarchical sensitivity coefficients measure the sensitivity of the response to three sets of interrelated parameters; namely, panels (or shells), layer and micromechanical parameters. The computational procedure is applied to the nonlinear static and postbuckling responses of composite shells and panels, as well as to sandwich structures with composite face sheets. The sensitivity coefficients are used in conjunction with fuzzy set techniques to study the range of variation of various response quantities associated with pre-selected variations of the major parameters.
