Effects of microstructural heterogeneity on the macroscopic spectrum of elastically accommodated grain-boundary sliding
Zhengxuan Li, John F. Rudge
Elastically accommodated grain-boundary sliding (EAGBS) is a plausible source of upper-mantle seismic attenuation and dispersion, yet classical theory predicts a localized Debye-li…

The viscoelastic rheology of transient diffusion creep
John F. Rudge
Polycrystalline materials have a viscoelastic rheology where the strains produced by stresses depend on the timescale of deformation. Energy can be stored elastically within grain…

A crystallographic approach to symmetry-breaking in fluid layers
John F. Rudge, Dan McKenzie
Symmetry-breaking bifurcations, where a flow state with a certain symmetry undergoes a transition to state with a different symmetry, are ubiquitous in fluid mechanics. Much can be…
