NTU-CEE Seminar Series: Dr. Patrick Brewick

Organized By

CEE Seminar Committee

Host By

Assistant Professor Fu Yuguang

Topic

Building Better Models for Mechanical and Dynamical Systems under Uncertainty

About the Seminar

Engineers rely upon models every day in a variety of contexts, up to an including the digital twins that are emerging as an increasingly essential tool for designing, maintaining, and monitoring infrastructure. Unfortunately, as the aphorism goes, “all models are wrong.” Engineers should not lose hope, though, because models can still become useful when they are informed by measurements and observations.

In this context, the importance of properly leveraging experimental data and field observations for informed model selection and careful parameter estimation becomes apparent. However, the inherent and ubiquitous presence of structural and parametric uncertainties add significant layers of complexity to these modeling tasks, necessitating the use of uncertainty quantification tools such as Bayesian inference.

This presentation will present a series of projects located at this nexus of data, modeling, mechanics, and uncertainty. Applications include using novel response data from distributed fiber optics for modal identification, creating hierarchical Bayesian approaches for distributed fiber optic strain sensing, and selecting the most probable nonlinear hysteretic models for seismic isolation systems.

About the Speaker

Patrick Brewick is currently an Assistant Professor in the Department of Civil and Environmental Engineering & Earth Sciences at the University of Notre Dame. Dr. Brewick earned his B.S. (2009) in Civil Engineering from the University of Notre Dame and M.S. (2010) and Ph.D. (2014) in Civil Engineering and Engineering Mechanics from Columbia University.

After his Ph.D., Dr. Brewick spent two years as a Viterbi Postdoctoral Fellow at the University of Southern California in the Sonny Astani Department of Civil and Environmental Engineering. Following his postdoc, Dr. Brewick spent several years as a Research Scientist in the Materials Science and Technology Division of the U.S. Naval Research Laboratory before joining the University of Notre Dame.
