The application of piezoelectric sensors such as the ultrasonic transducer has significantly
enhanced the fields of nondestructive evaluation (NDE). Their application of piezoelectric …

Yield stress materials fail when the imposed stress crosses a critical threshold. A well-known
dynamical response to the applied stress is the phenomenon of creep where the cumulative …

This chapter reviews some emergent properties of the dynamics of glassy systems, and
more generally of a wide class of disordered systems. In a first contribution (Sec. 15.1) …

A wide range of materials can exist in microscopically disordered solid forms, referred to as
amorphous solids or glasses. Such materials–oxide glasses and metallic glasses, to …

We investigate, using a recently developed model of liquid state theory describing the
rheology of dense granular flows, how a yield stress appears in granular matter at the …

Amorphous materials span a wide range of systems, including foam bubbles, colloidal
molecules, and polymer strands. Regardless of their composition, they all share the common …

We present a finite-size study of the athermal quasistatic yielding transition in structural
glasses featuring a wide range of mechanical disorder. We find a crossover from gradual …

337 becomes stationary and the dynamics becomes time-translational invariant. Flow curve
For yield stress fluids, one can establish a flow curve given by the steady state average …

We explore the mechanics of amorphous systems using two types of models. In the first, we
study a multi-body finite element model of a packing of hydrogel particles. We show that …

In this thesis, I investigate various non-equilibrium systems and analyse statistics relating to
thermodynamic and rheological observables. I start by theoretically considering a cyclically …
