The impact-activated solidification of cornstarch suspensions has proven to be a multi-faceted problem and a complete explanation of the different phenomena observed during this process remains elusive. In this work, we revisit this rich problem and

The maximum strength theorem is applied to determine the pressure conditions in accretionary wedges responsible for the activation of splay faults (SF). This theorem, based on the limit analysis developed in soil mechanics, selects among several mode

Suspensions of cornstarch in water exhibit strong dynamic shear-thickening. We show that partly replacing water by ethanol strongly alters the suspension rheology. We perform steady and non-steady rheology measurements combined with atomic force micr

International audience; We propose a dynamical mechanism leading to the fluidization by external mechanical fluctuations of soft-glassy amorphous material driven below the yield stress. The model is based on the combination of memory effect and nonli

Deformation and stability of over-pressured wedges: Insight from sandbox models

[1] In the well-known and widely used critical taper model of accretionary wedges, pore pressure is introduced as a first-order parameter. Despite the fact that the importance of the pore pressure on deformation is largely accepted, the theoretical p
