Journal ArticleDOI
Reengineering Aircraft Structural Life Prediction Using a Digital Twin
TL;DR: A conceptual model of how the Digital Twin can be used for predicting the life of aircraft structure and assuring its structural integrity is presented and the technical challenges to developing and deploying a Digital Twin are discussed.
Journal ArticleDOI
A review of indirect/non-intrusive reduced order modeling of nonlinear geometric structures
TL;DR: In this article, a review of reduced order modeling techniques for geometrically nonlinear structures, more specifically those techniques that are applicable to structural models constructed using commercial finite element software, is presented.
Journal ArticleDOI
Nonlinear modal models for sonic fatigue response prediction: a comparison of methods
TL;DR: In this article, several methods used to construct the nonlinear modal models are compared using a clamped-clamped beam as an example problem, and the modal equations can then be integrated in the time domain.
Journal ArticleDOI
Exploring the response of a thin, flexible panel to shock-turbulent boundary-layer interactions

TL;DR: In this paper, the effect of turbulent, heated flow and sensitivity to panel back-pressure modulation was studied, with large deformation limit cycle behavior leading to panel failure, observed and measured.
Journal ArticleDOI
Progressive failure analysis of a composite shell
TL;DR: In this article, the authors determine the physical response including material failure of a thin, curved composite panel designed to resist transverse loading through failure criterion based on nonlinear movement using a finite element analysis technique.
