“Parametric Modeling and Isogeometric Analysis of Complex Engineering Structures”
Abstract
Despite numerous technological developments over the last few decades, considerable obstacles remain in the practical design and scientific analysis of complex engineering structures. Additionally, for many applications, real-world engineering systems can be difficult or prohibitive to study experimentally due to the scale, cost, and accessibility of the systems. In such cases, computational methods provide a suitable alternative for scientific investigation. This talk will discuss approaches for addressing some of the fundamental challenges associated with the modeling and analysis of various complex science and engineering applications. Specific applications include wind energy systems, aerospace structures, and bioprosthetic heart valves. Effective simulation approaches for numerous science and engineering problems are proposed, and innovative solutions are also presented for the design and parameterization of engineering structures, which can facilitate data-oriented research, including design optimization, sensitivity analysis, uncertainty quantification, and machine learning.
