The rotator cuff as a bi-material interface
Abstract:
Joining of dissimilar materials is a fundamental challenge in engineering. Nature presents a highly effective solution at the attachment of tendon to bone ("enthesis") in the rotator cuff of the shoulder’s humeral head. The natural enthesis does not regrow following healing or surgery, resulting in inferior tissue and in post-surgical tear recurrence rates as high as 94%. Pressing needs exist both to understand the mechanobiology of adhesion and toughening across hierarchical scales in the healthy enthesis, and to reconstitute these in healing.
Our results show the tendon to bone insertion to be a hierarchical, heterogeneous, disordered system that uses randomness to tailor strain fields, and to maximize the fraction of tissue involved in resisting injury-level stresses. Based upon this model, we are developing two new mechano-medicine products for clinical translation: a diagnostic technology to evaluate the degree to which an enthesis is succeeding in physiological strain redistribution, and a repair technology that mimics the mesoscale function of the healthy enthesis by maximizing the fraction of tissue involved in resisting injury-level stresses. This talk will summarize our understanding of the mechanics of tendon-to-bone attachment, and describe repair and imaging technologies under development that harness this with the goal of providing improved surgical outcomes.

lessOn the Design and Manufacture of Structures for Flightworthy Gas Turbines
by Apostolos Karafillis
Chief Consulting Engineer
Structures and Additive Design
GE Aerospace
Abstract
The design and manufacture of gas turbine components presents unique technical challenges that highlight the relevance and importance of the disciplines of mechanical and aerospace engineering. In this presentation, we will focus on describing the fundamental technical requirements for parts of flightworthy gas turbines and will then share examples of designs and innovations to meet these requirements. The talk will include the description of typical loading conditions and operating environments, and the description of how these requirements guide the selection of design features, materials, and manufacturing methods. We will discuss three specific examples: The selection of features and architecture of a bearing housing, the design of a turbine frame with a mix of metallic and composite materials, and the development of methods for characterizing the performance of components manufactured with non-traditional methods. Through these examples, it will be shown that successful hardware design requires the combination of robust design methods, rigorous implementation of the principles of mechanics of materials, and the development of design and manufacturing innovation.TIME Tuesday, April 30, 2024 at 2:00 PM - 3:00 PM

Speaker: Russ Tedrake, Toyota Professor of EECS, Aero/Astro, ME at Massachusetts Institute of Technology and VP of Research at Toyota Research Institute
Title: Dexterous Manipulation with Diffusion Policies
Date and Time: Friday, May 3 at 11:30 AM CT
Location: Tech ESAM M416 and Zoom

Abstract:
At the Toyota Research Institute (TRI), we've been working on behavior cloning for dexterous manipulation. Building on the Diffusion Policy framework that we've recently developed in collaboration with Shuran Song, we now have a very solid pipeline for taking ~50-100 bimanual haptic teleop demonstrations and turning that into a surprisingly effective visuomotor (+tactile) policy. Because there is no explicit state representation required, these skills work equally well manipulating deformable, liquid, or other difficult to model tasks as they do for more traditional rigid-object manipulation. We're actively scaling this up into the multi-task setting and now see a plausible path towards "Large Behavior Models". This behavior cloning pipeline is working incredibly well, and must be understood deeply in the broader context of output-feedback control. Time permitting, I'll also tell you a bit about some new results in optimization-based planning and control, and where they might fit in the age of foundation models.

lessThe Center for Scientific Studies in the Arts is a collaboration between the Art Institute of Chicago and materials science-related departments at Northwestern University to pursue objects-based and objects-inspired scientific research. Materials research benefits ongoing work in conservation, archaeology, art history, and curatorial scholarship.
Learn how the Center uses materials research to care for art objects in sustainable, innovative ways with Maria Kokkori, Senior Scientist in the Center for Scientific Studies in the Arts. She will be in conversation with Corey Byrnes, Northwestern Associate Professor of Chinese Culture and co-founder/co-director of the Environmental Humanities Workshop in Kaplan Humanities Center.
This event is presented by the McCormick School of Engineering and Applied Science in conjunction with exhibition Actions for the Earth: Art, Care & Ecology.
