Droplet coalescence in fluids obeying Darcy's law
Jing Wang, Haicen Yue, Nandish Vora +4
During drop coalescence, a connecting bridge of fluid forms and rapidly expands due to surface tension. For spherical drops, these dynamics are well understood in both the viscous…
Dual Role for Heterogeneity in Dynamic Fracture
Itamar Kolvin, Mokhtar Adda-Bedia
We approach the problem of heterogeneous dynamic fracture by considering spatiotemporal perturbations to planar crack fronts. Front propagation is governed by local energy balance…
A comprehensive study of nonlinear perturbations in the dynamics of planar crack fronts
Itamar Kolvin, Mokhtar Adda-Bedia
The interaction of crack fronts with asperities is central to the criteria of fracture in heterogeneous materials and for predicting fracture surface formation. It is known how dyn…
Active assembly and non-reciprocal dynamics of elastic membranes
John Berezney, Sattvic Ray, Itamar Kolvin +6
Equilibrium self-assembly and conventional materials processing techniques fall far short of mimicking dynamic self-actuating processes that are commonplace throughout biology. To…
