MEAM Seminar: “Dynamic Response of Resonant Metamaterials and Other Composites”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Composite materials under dynamic loading exhibit interesting emergent phenomena. Most notably are phononic crystals and metamaterials which can possess frequency dependent and negative elastic moduli and density. In general, the constitutive response is non-local in space and time and depends on both the strain and velocity. Additionally, scattering and local resonance effects can lead to […]

MEAM Seminar: “Towards Manipulation of Large Objects by Robotic Edge Rolling with Quori, an Affordable Socially Interactive Humanoid Robot”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Hardware platforms for socially interactive robotics can be limited by cost or lack of functionality. In this talk I will present the overall system—design, hardware, and software—for Quori, a novel, affordable, socially interactive humanoid robot platform for facilitating non-contact human-robot interaction(HRI) research. The design of the system is motivated by feedback sampled from the HRI […]

MEAM Seminar: “Nanocellulose Fibers as Reinforcement to Improve Strength and Toughness in Structural Materials”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Cellulose nanofibrils (CNFs) are a naturally abundant polymer and have superior mechanical properties, high aspect ratios, are transparent and biodegradable, which make them attractive to be used in structural materials. As a reinforcing phase, CNFs have the potential to improve the mechanical properties of polymer materials. While there are active research efforts aimed at incorporating […]

MEAM Seminar: “A Methodology for Self-Replicating Robots from Ice”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

In the late 1940s, John von Neumann first introduced the concept of self-replication as a way of furthering cellular reproduction research. By the late ‘50s and ’60s this research diverges along two separate paths: cellular automata replication with a focus on biological systems and robotics/machine replication. Generally the work in robotic systems focuses on the […]

MEAM Seminar: “Rheological Behavior and Field Statistics of Suspensions of Rigid Particles in Yield Stress Fluids”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Suspensions of non-Brownian particles in fluids are commonly found in nature (e.g. mud, soils, and debris flows) and in the industry (e.g. paints, food, and cosmetics). Understanding the relations between the microstructure and the effective properties of these materials can provide insight into how they fail or behave during processing. Despite their ubiquity and usefulness, […]

MEAM Seminar: “Some Investigations of Phase Transitions in Rod-like Macro-molecules and Fibrous Gels”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Stress-induced solid-to-solid phase transitions form a large class of phase transitions in nature. They occur in materials that can exhibit different crystal structures under different conditions (stress and temperature), and when the stress and temperature condition changes, the material may undergo a transformation from one phase to another. Despite its considerable potential in application, some […]
