Astani Department of Civil and Environmental Engineering Seminar
Tue, Feb 16, 2021 @ 11:00 AM - 12:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Chung-Yuen (Herbert) Hui, Proessor, Cornell University
Talk Title: The role of surface stress on the mechanical behavior of soft solids
Abstract: Soft solids are ubiquitous: gels, foams, biomaterials, rubbers, and the stuff that makes up our very bodies. They are orders of magnitude more compliant than conventional engineering materials (e.g., stiff materials such as metals and ceramics). For this reason, the mechanical behavior of stiff solids is controlled by the resistance to bulk deformation: elasticity, plasticity, and the like; the mechanical role of the surface is utterly negligible, as noted by Gibbs. However, the surface of common soft solids carries considerable stress, just as liquids have a surface tension. Consequently, for soft solids, the pervasive influence of surface stress has required re-thinking a wide range of mechanical phenomena and properties. In this talk, I will show examples of phenomena where surface stress has radically changed mechanical behaviour. For example, how small particles interact with soft substrates can be governed more by surface stress than by the elasticity of the substrate. Surface stress can modify adhesion on rough surfaces by flattening them. The contact angle in partial wetting is no longer always governed by Young equation -“ it depends on the surface stress of the solid substrate as well as its elasticity.
Biography: Dr. Chung-Yuen(Herbert)Hui is the Joseph-Ford Professor of Mechanical and Aerospace Engineering(MAE)of Cornell University. He has a Bachelor of Science degree from the University of Wisconsin-Madison majoring in Physics and Mathematics. He received his Master degree in Applied Math and Ph.D.degree in Solid Mechanics from Harvard. He joined the Department of Theoretical and Applied Mechanics(TAM)at Cornell University in 1981 and stayed until 2010, when TAM became part of MAE. His primary research interest is Physics and Mechanics of materials. His recent research is primarily focused on adhesion science, fracture mechanics and mechanics of soft matter. He was the Chairman of Gordon Conference on Adhesion in 2010 and received the Adhesion Society Award for Excellence in Adhesion Science in 2011. He enjoys teaching and received several teaching awards including Tau-Beta-Pi Excellence in Teaching Award.

PhD Thesis Proposal - Hexiang Hu
Tue, Feb 16, 2021 @ 04:00 PM - 05:00 PM
Thomas Lord Department of Computer Science
University Calendar
Title of the Presentation:
Understanding Language in Perception and Embodiment
Committee: Fei Sha (Chair); Jay Kuo, Joseph Lim, Jesse Thomason, Robin Jia
Abstract:
Neural networks have made impressive progress in Natural Langauge Processing, which positively influenced many real-world tasks. Despite their success, language learners are often constrained as they are exposed only to the text world (from curated corpus or the internet). Consequently, language learners can not associate the learned distributional semantics with their appearance and affordance in the physical world. In this thesis proposal, I discuss approaches that learn to understand the language in the context of the visual dynamic world, which associate the hierarchical language expressions (such as word, phrase, sentence, and paragraph) with dynamic visual content (such as image and video). Moreover, I also discuss the future directions to understand the language in the embodied environment.

AME Seminar
Wed, Feb 17, 2021 @ 03:30 PM - 04:30 PM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Ian Tobasco, Univ. Illinois Chicago
Talk Title: Simple Rules for the Wrinkle Patterns of Confined Elastic Shells
Abstract: Dried fruits wrinkle for the same reason that leaves and flowers do -” mechanical instabilities arising from a mismatch in lengths. Can such geometric incompatibilities be used to design and control wrinkle patterns at will? This talk will discuss the possibility of designing wrinkle patterns in the large using a recently derived model for the wrinkles of confined elastic shells. After recalling the basic mechanics and introducing our model, we show how it can be solved by hand in many cases to predict the wrinkled topography. Solving this model produces a few geometric rules, which explain the layout of the wrinkle peaks and troughs across examples. These simple rules reproduce the patterns seen in numerous experiments and simulations, even ones that exhibit a surprising coexistence between orderly wrinkles and a more disordered response. Knowing such rules for wrinkles opens the way towards designer wrinkle patterns, with potential applications from flexible electronics to synthetic skins.
Biography: Ian Tobasco is an Assistant Professor at the University of Illinois at Chicago Department of Mathematics, Statistics, and Computer Science. He holds a Ph.D. in Mathematics from the Courant Institute of Mathematical Sciences at New York University, and a B.S.E. in Aerospace Engineering from the University of Michigan.
His research on the calculus of variations and partial differential equations concerns problems that sit at the interface of mathematics, physics, and engineering, where advances in pure mathematical analysis can lead to scientific breakthroughs in the lab and vice versa. His recent work involves the use of energy minimization to explain and classify the zoo of wrinkling, crumpling, and folding patterns exhibited by thin elastic sheets. Other interests include the design of optimal transport mechanisms in fluid dynamics and their comparison with naturally occurring turbulent transport, as well as the variational analysis of spin glasses.

AME PhD Student Seminar
Fri, Feb 19, 2021 @ 03:00 PM - 04:00 PM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Speaker: Raye Xie, USC AME PhD Student
Talk Title: Development and Validation of a Body-Force Propulsor
Abstract: This talk introduces a body-force propulsor model that replaces the engine blades with a source volume in CFD to produce the equivalent flow turning, work input, and losses. The motivation for developing this model is to capture the effects of inlet flow non-uniformity on propulsor performance, while using a local formulation appropriate for full-aircraft CFD at a computational cost compatible with design studies. The model is able to capture non-axisymmetric effects and only requires specification of the blade camber and thickness distributions. An inviscid formulation for the body-force was previously found to be capable of predicting the inviscid distortion transfer effects, but losses and blade metal blockage effects were not accounted for. An improved formulation with a blockage component is proposed here and is shown to properly predict the propulsor work. Loss terms are included to model 2D profile losses and secondary flow losses. The proposed model is implemented in the flow solver ADflow and validated against NASA rotor 67 experimental data.
Biography: Tianbo (Raye) is a PhD student supervised by Dr. Alejandra Uranga. His research focuses on engine/propulsor modeling in high-fidelity simulations and full-aircraft simulations. Raye has a B.S. from Rensselaer Polytechnic Institute, and a M.S. from USC.
