Solids are rigid, which means that when left undisturbed, their structures are nearly static. It
follows that these structures depend on history—but it is surprising that they hold readable …

During the last fifteen years there has been a paradigm shift in the continuum modelling of
granular materials; most notably with the development of rheological models, such as the …

Frictional sliding between patterned surfaces is of fundamental and practical importance in
the haptic engineering of soft materials. In emerging applications such as remote surgery …

The soft part of the Earth's surface–the ground beneath our feet–constitutes the basis for life
and natural resources, yet a general physical understanding of the ground is still lacking. In …

Non-Newtonian fluids have a viscosity that varies with applied stress. Elastoviscoplastic
fluids, the elastic, viscous and plastic properties of which are interconnected in a non-trivial …

When wet soil becomes fully saturated by intense rainfall, or is shaken by an earthquake, it
may fluidize catastrophically. Sand-rich slurries are treated as granular suspensions, where …

The ability to concisely describe the dynamical behavior of soft materials through closed-
form constitutive relations holds the key to accelerated and informed design of materials and …

Self-organization, and transitions from reversible to irreversible behavior, of interacting
particle assemblies driven by externally imposed stresses or deformation is of interest in …

A fundamental challenge regarding disordered solids is predicting macroscopic yield—the
point at which elastic behaviour changes to plastic behaviour—from the microscopic …

Structural systems involving mobile shale represent one of the most difficult challenges for
geoscientists dedicated to exploring the subsurface structure of continental margins. Mobile …
