Abstract

The focus of this investigation is on assessing the use of nonintrusive (i.e. developed directly from commercial finite element codes) nonlinear reduced order modeling techniques for the prediction of the strongly nonlinear response of joined wings, e.g. the snap-buckling they exhibit. A key component of the reduced order modeling is the selection of the basis to represent the response and this aspect will be extensively discussed leading to the formulation of new metrics for the assessment of the basis. The reduced order models constructed with bases satisfying these metrics performed well in capturing the strongly nonlinear events in comparison to the predictions of the finite element code from which they are derived.
