(Department of Theoretical and Applied Mechanics (UIUC), 200508)The classical experiments on turbulent friction in rough pipes were performed by J. Nikuradse in the 1930s. Seventy years later, they continue to defy theory. Here we model Nikuradse’s experiments using the phenomenological ...

(1984)Two problems are studied in this dissertation. In the first problem, surface motion, excited by acoustic emissions produced by fracture processes at the edge of a buried, pennyshape crack, are investigated. First, wavefront ...

(American Physical Society, 2002)When poured into a container, cohesive granular materials form lowdensity, open granular aggregates. If pressure is applied to these aggregates, they densify by particle rearrangement. Here we introduce experimental and ...

(Department of Theoretical and Applied Mechanics (UIUC), 200506)Using a geometrical approach to treat the constraints associated with the continuum description of uniaxial nematic elastomers, we develop the general constitutive framework for such materials. We also provide a variational ...

(Department of Theoretical and Applied Mechanics (UIUC), 200109)Guided by the kinematical treatment of vacancies in theories for solidstate diffusion, we develop a theory for compaction and segregation in flowing granular materials. This theory leads to a partial differential equation ...

(Department of Theoretical and Applied Mechanics (UIUC), 200509)Photographs of a volcanic column in a recent eruption of Reventador show a prominently scalloped umbrella that is unlike any umbrella previously documented on a volcanic column. We propose that the scallops in this umbrella ...

(Department of Theoretical and Applied Mechanics (UIUC), 200210)Vortex crystals is one name in use for the subject of vortex patterns that move without change of shape or size. Most of what is known pertains to the case of arrays of parallel line vortices moving so as to produce an ...
