Tedori-Callinan Lecture: “Resist Fatigue by De-concentrating Stress”
Most materials suffer from a disease: fatigue. Symptoms include degradation of properties and growth of cracks under cyclic stretch. These materials are unfit for applications involving prolonged and cyclic loads. […]
MEAM PhD Thesis Defense: “Dynamic Behavior of Periodic Media and Elastic Metamaterials”
Periodic media and resonant, acoustic/elastic metamaterials possess extraordinary frequency band gaps where no waves may propagate. In this dissertation, we leverage numerical simulations to gain insight into practical ways to […]
MEAM PhD Thesis Defense: “A Differential Homogenization Framework for Precipitation-Strengthened Metals”
Composite materials, such as metal- and polymer-matrix composites, exhibit both elastic and dissipative effects when subjected to macroscopic loadings. Even when the phases of the composite are characterized by a […]
MEAM PhD Thesis Defense: “Analytical Homogenization Estimates for the Effective Properties and Field Statistics of Viscoplastic Composites and Particle Suspensions”
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 […]
MEAM Seminar: “Robotics Goes Soft: Challenges and Achievements, for New Robotics Scenarios”
Largely inspired by the observation of the role of soft tissues in living organisms, the use of soft materials for building robots is recognized as one of the current challenges […]
MEAM Seminar: “Electrets, Magnetics and Deformation in Soft Materials”
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 […]
MEAM Seminar: “Computational Mechanics for Landing on Mars”
Current technology for decelerating a spacecraft from the high speed of atmospheric entry to the final stages of landing on Mars is based on low-density supersonic decelerators such as low […]
