Universal shapes formed by two interacting cracks
Melissa L. Fender, Frederic Lechenault, Karen E. Daniels
We investigate the origins of the widely-observed "en passant" crack pattern which forms through interactions between two approaching cracks. A rectangular elastic plate is notched…
Scalar conservation laws with nonconstant coefficients with application to particle size segregation in granular flow
Lindsay B. H. May, Michael Shearer, Karen E. Daniels
Granular materials will segregate by particle size when subjected to shear, as occurs, for example, in avalanches. The evolution of a bidisperse mixture of particles can be modeled…
Equilibration of granular subsystems
F. Lechenault, Karen E. Daniels
We experimentally investigate the steady states of two granular assemblies differing in their material properties and allowed to exchange volume with each other under external agit…
