A reduced-order stochastic finite element approach for design optimization under uncertainty

Autor: Gary Weickum, Kurt Maute, Mike Eldred

Publikováno v: Structural Safety. 31:450-459

This paper presents a computational framework for structural design optimization under uncertainty. The stochastic static response of linear elastic structures is predicted by a spectral stochastic finite element method (SSFEM) based on a polynomial

Multi-point Extended Reduced Order Modeling For Design Optimization and Uncertainty Analysis

Autor: Gary Weickum, Mike Eldred, Kurt Maute

For large computational models, standard deterministic optimization approaches can be prohibitively expensive due to the need to repeatedly evaluate the model. This difficulty is amplified when stochastic aspects of the model are included, such as in
