Talk Title: The Finite Element Method and Isogeometric Analysis: Past, Present, Future
Abstract: I will begin by probing into the past to discover the origins of the Finite Element Method (FEM), and then trace the evolution of those early developments to the present day in which the FEM is ubiquitous in science, engineering, mathematics, and medicine, and the most important discretization technology in Computational Mechanics. However, despite its enormous success, there are still problems with contemporary technology, for example, building meshes from Computer Aided Design (CAD) representations is labor intensive, and a significant bottleneck in the design-through-analysis process; the introduction of geometry errors in computational models that arise due to feature removal, geometry clean-up and CAD “healing,” necessary to facilitate mesh generation; the inability of contemporary technology to “close the loop” with design optimization; and the failure of higher-order finite elements to achieve their full promise in industrial applications. These issues are addressed by Isogeometric Analysis (IGA), the vision of which was first presented in a paper published October 1, 2005 [1]. Since then, IGA has become a focus of research within both FEM and CAD and is now a mainstream analysis methodology that has provided a new paradigm for computational model development [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. I will briefly present the motivation leading to IGA, its status, recent progress, areas of current activity, and what it offers for analysis model development and the design-through-analysis process. I will also argue that IGA provides an alternative and more robust approach to higher-order finite element analysis, filling the gap between low-order, geometrically versatile approaches and high-order, geometrically restrictive spectral methods. Finally, I will speculate on the future, the technologies that will prevail, computer developments, and the role of machine learning. [1] T.J.R. Hughes, J.A. Cottrell and Y.

AAI-CCI-MHI Seminar on CPS
Wed, Aug 28, 2024 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Speaker: Sonia Roberts, Assistant Professor Wesleyan University
Talk Title: From legged robots to knitted ones
Series: EE598 Seminar Series
Abstract: Traditional robotics assumes rigid bodies interacting with rigid environments. However, the real world is soft. Robots will need to be able to move over materials like sand, snow, and leaf litter, and will need to be able to interact with fruits, fabrics, and of course humans. I will discuss two types of soft interactions between a robot and the world: Robot locomotion on granular media, and the use of knitting as a computational fabrication method to create soft sensors for robots.
Biography: Dr. Sonia Roberts is an Assistant Professor of Computer Science at Wesleyan University working on knitted sensors for soft robot skins and legged robot locomotion on granular media. In 2023, she completed a postdoc with Prof. Kris Dorsey at Northeastern as part of the Institute for Experiential Robotics, where she worked on soft origami sensors. She received her PhD in Electrical and Systems Engineering from the University of Pennsylvania in 2021, where she worked with Prof. Dan Koditschek in the GRASP Lab to develop a reactive controller to reduce the energetic cost of transport for legged robots on sand. Prior to coming to Penn, Sonia worked at Janelia Farm Research Campus on a team building a rough behavioral map of the fruit fly brain, and with John Long using evolutionary robotics tools to answer biological questions at Vassar College.
