Isogeometric analysis: mathematical and engineering perspectives

Thomas J.R. Hughes, Professor, Aerospace Engineering and Engineering Mechanics, Oden Institute, UT Austin

Abstract

**This seminar will be presented LIVE in POB 6.304 and via Zoom.**

The vision of Isogeometric Analysis (IGA) was first presented in a paper published October 1, 2005 [1]. Since then it has become a focus of research within both the fields of Finite Element Analysis (FEA) and Computer Aided Design (CAD) and has become a mainstream analysis methodology and provided a new paradigm for geometric design [2-4]. The key concept utilized in the technical approach is the development of a new foundation for FEA, based on rich geometric descriptions originating in CAD, more tightly integrating design and analysis. Industrial applications and commercial software developments have expanded recently. In this talk, I will present mathematical and engineering perspectives on IGA as an FEA technology and some examples of recent research directions.

Key Words: Computational Mechanics, Computer Aided Design, Finite Element Analysis, Computer Aided Engineering
