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.

TL;DR: In this article, a non-linear structural dynamic reduced-order model for aircraft panels is proposed, with particular emphasis on aircraft panels, and the model is validated for isotropic/symmetric composite structures and then extended to asymmetric and functionally graded ones.

TL;DR: In this article, the use of intentional mistuning of bladed disks to reduce their sensitivity to unintentional random mistuning is investigated, and a two-step procedure is described to optimize the arrangement of these blades around the disk to reduce the effects of unintentional mistuning.

TL;DR: In this article, the authors investigated the local and global effects of mistuning on the forced response of bladed disks and found that the largest amplification due to the mistuning occurs at very strong blade-to-blade coupling levels, at contrary of a general perception, but is associated with large mistuning levels.

TL;DR: In this article, the authors developed and validated a reduced-order model for the geometrically nonlinear response and temperature of heated structures, based on a modal-type expansion of both displacements and temperatures in the undeformed, unheated configuration.
