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 […]

MEAM Seminar: “Exploiting Interface Patterning for Adhesion Control”

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

Surface force-mediated adhesion, e.g. van der Waals forces, is critical for direct bonding of bulk solids in the absence of an adhesive layer. However, no two surfaces are ideally flat or perfectly conformal due to surface roughness or intentional patterning. When in the adhered state, non-zero surface tractions arise wherever the local separation of the […]

MEAM Seminar: “A Differential Homogenization Framework for Precipitation Strengthened Metals”

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

Precipitation-strengthened alloys are a commercially important class of materials because their mechanical properties can be altered by changing the microstructure through heat-treatment. Specifically, precipitates are introduced into the bulk (matrix) material to interact with dislocations and affect their mobility. It is known that the size, shape, orientation and stiffness of the precipitates, which can be […]

MEAM Seminar: “Accelerated Design of Heterogeneous Materials for Improved Failure Characteristics”

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

Nature provides countless examples of the use of heterogeneity to enhance the failure properties of materials. Many biological materials, such as bone, marine shells, and fish scales, are extremely resilient to fracture and failure. These often consist of regions that are highly mineralized and stiff and regions of biopolymers that are extremely soft. In practice, […]

MEAM Seminar: “Metal and Air Generate Power for Robots”

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

In many cases, the size and weight of energy storage technologies required to power robotic systems are too large or massive for a robot to carry, leading to limited operational times and long recharging times over which the robot remains unused. Computer-free autonomous decision making based on environmental cues provides exciting alternatives to classic control […]

MEAM Seminar: “Deep Learning and Uncertainty Quantification: Methodologies and Applications”

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

Uncertainty is ubiquitous in physical and engineering science because of the lack of knowledge, inaccuracy in measurements, objective stochastic nature. “You cannot be certain about uncertainty”. Uncertainty quantification plays an essential role in decision making, solutions of partial differential equations, optimal design, etc. However, quantifying the uncertainty is not trivial in computational science. The difficulty […]
