MEAM Seminar: “Electrets, Magnetics and Deformation in Soft Materials”

October 5 at 10:00 AM - 11:30 AM
Zoom – Email MEAM for Link, peterlit@seas.upenn.edu

Soft robotics, energy harvesting, large-deformation sensing and actuation, are just some of the applications that can be enabled by soft dielectrics that demonstrate substantive electromechanical coupling. Imagine now also a material that will produce electricity and deform substantively via a contactless, wireless magnetic signal. Unfortunately, truly soft, naturally occurring piezoelectric or magnetoelectric materials essentially do […]

MEAM PhD Thesis Defense: “Analytical Homogenization Estimates for the Effective Properties and Field Statistics of Viscoplastic Composites and Particle Suspensions”

October 5 at 1:00 PM - 2:00 PM
Zoom – Email MEAM for Link, peterlit@seas.upenn.edu

Heterogeneous materials are commonly found in nature (e.g. soil, rock, blood) and engineering applications (e.g. paints, lubricants, sintered materials). Understanding the microstructure-properties relations is crucial to predicting how these materials fail and behave during processing. In this thesis, we develop semi-analytical homogenization estimates for the macroscopic properties and field statistics of viscoplastic composites. A generalization […]
