Bubbles bursting at contaminated water surfaces aerosolize oil, microplastics and bacteria, with consequences for public health and climate. The classical description, in which a draining cap ruptures at a single hole and the retracting rim fragments into film droplets, was...
In direct ink writing (DIW), yield-stress materials are formulated to retain their shape post-extrusion; however, this same resistance to flow can prevent intra- and inter-filament pores from closing. Such residual porosity compromises the mechanical integrity of printed pastes, ceramics, and...
Periodic structures, built by repeating a single unit cell in space, can be designed to control how elastic waves propagate. Their dispersion relation, obtained from one cell through Bloch’s theorem, reveals band gaps: frequency ranges in which no wave can...
Multistable metamaterials are engineered structures capable of reconfiguring between distinct equilibrium states, offering extraordinary functionality, such as substantial energy dissipation and nonlinear wave propagation. However, current implementations rely predominantly on macroscale, polymer-based fabrication, resulting in architectures suffering from geometric defects,...
Flexible rod-like objects such as cables, wires and hoses appear in assembly, maintenance and household tasks, yet their manipulation by robot arms remains difficult. Unlike a rigid body, the shape of a flexible object is determined by the positions and...

Fracture surfaces contain evidence of a material’s condition and loading history. Scanning electron microscopy (SEM) reveals this evidence in detail, but interpreting and comparing large collections of fracture images remains strongly dependent on expert judgment. This research develops an automated...
Liquid Metal Embrittlement (LME) is a phenomenon in which the interaction between a solid metal and a penetrating liquid metal can lead to a significant reduction in ductility and fracture resistance. Although liquid metal penetration along grain boundaries is widely...
This talk describes the derivation of optimal, semi-analytic, algebraic equality conditions that can be used to identify second-moment stability boundaries in linear, time-invariant stochastic delay-differential equations with a single constant delay and both multiplicative and additive noise, without the use...
