MEAM / ASSET Seminar: “Generative Constitutive Laws as Graphs and Trees”
Capturing path- and rate-dependent behaviors of solids, such as creeping, plastic deformation, damage, and fracture, often requires interpreting and quantifying relationships among the histories of variables, such as dislocation density […]
MEAM Seminar: “Mechanics of Architected Materials Across Length and Time Scales”
Architected materials (or mechanical metamaterials) across length scales—from nanometers to centimeters—have enabled previously unachievable mechanical properties through a variety of 3D material morphologies. Significant advances in our understanding of these […]
MEAM Seminar: “Physical and Neural Reservoirs for Mechanically Intelligent Sensing and Control”
Reservoir computing is an information processing paradigm within which the nonlinear dynamics of a system are exploited to perform information processing. While originally proposed in the context of artificial and […]
MEAM Seminar: “The Secret Life of Interfaces: Solute-Rich Films, Slippery Ice, and Continuous Emulsions”
Phase change concentrates the action into a narrow region near the moving interface, where composition, transport, and interfacial disorder evolve rapidly and determine macroscopic outcomes. In this talk, I will […]
MEAM Seminar: “A ‘Full Stack’ Problem”
While many of the tremendous advances seen in robotic dexterity over the past half-decade have been driven by new motor learning methods, I remain convinced that manipulation is a “full […]
MEAM Seminar: “From Rogue Waves to Origami: Energy Focusing and Dissipation in Mechanical Metamaterials”
Mechanical metamaterials offer unique opportunities to focus or dissipate energy through controlled wave dynamics. I will first present experimental studies of wave localization in one-dimensional nonlinear lattices, where we observed […]
MEAM Seminar: “Multiscale Biomechanics and Mechanobiology of the Aortic Aneurysm, or How I Learned to Stop Worrying and Enjoy a Life of Stress and Failure”
Ascending thoracic aortic aneurysm (ATAA), an enlargement of the aorta near its exit from the heart, is largely harmless unless a vessel wall failure event occurs. A failure event, however, […]
MEAM Seminar: “Constitutive Modeling of Rubbery Networks: From Microscale Physics to Macroscopic Behavior”
Rubbery polymer networks, including elastomers and hydrogels, are increasingly employed in advanced applications such as biomedical implants, drug delivery systems, and smart sensors and actuators. Their macroscopic mechanical properties, such […]
MEAM Seminar: “Nonlinear Modeling, Synthesis, and Design-for-Additive Manufacturing of Smart Compliant Mechanisms”
Compliant mechanisms have been the subject of intense research in recent decades. Making compliant mechanisms “smart” to form flexible, adaptive structures is the focus of my research group, with applications […]
Eli Burstein Lecture in Materials Science: “Toward Intelligent Metamaterial Machines,” Katia Bertoldi – Harvard University
Flexible mechanical metamaterials are engineered structures whose unique geometries allow them to display remarkable behaviors, especially in the nonlinear regime. These systems hold promise for enabling the next generation of […]
