This work performs a direct comparison between generalized polynomial chaos (GPC) expansion techniques applied to structural acoustic problems. Broadly, the GPC techniques are grouped in two categories: , where the stochastic sampling is predetermine

This work explores the use of parallelized optimization techniques for structural acoustics problems. In particular, the underlying problems studied here utilize finite element substructuring in order to solve the objective function, though the subst

We seek here a computationally parsimonious and credible means to simulate the complex phenomena of vortex-induced vibrations (ViV), as one tool to assist in mitigating risk associated with ViV-induced instabilities that can cause non-negligible stru

Leaky-wave antennas (LWA) are commonly used in beam-steering situations such as radars, imaging, and other such frequency scanning applications. LWA are particularly useful metamaterials due to their relatively simple structure of repeated cells in a

This work explores generalized polynomial chaos (GPC) surrogate models and their effectiveness for general acoustics and vibration applications. GPC is primarily known as an uncertainty quantification (UQ) technique and in that context the underlying

We explore the use of generalized polynomial chaos (GPC) expansion with stochastic collocation (SC) for modeling the uncertainty in the noise radiated by a plate subject to turbulent boundary layer (TBL) forcing. The SC form of polynomial chaos permi
