Description

In this contribution, we will show that liquefaction can be treated as a diffuse instability, within the framework of bifurcation theory. Furthermore, for the first time, we will show that liquefaction instability has a micromechanical origin and explicitly show the necessary conditions to attain liquefaction from a micromechanical point of view. All of these findings are contrasted and shown to support all phenomenological observations corresponding to dense and loose sands.

Liquefaction in granular matter as a diffuse instability with micromechanical origin

In this contribution, we will show that liquefaction can be treated as a diffuse instability, within the framework of bifurcation theory. Furthermore, for the first time, we will show that liquefaction instability has a micromechanical origin and explicitly show the necessary conditions to attain liquefaction from a micromechanical point of view. All of these findings are contrasted and shown to support all phenomenological observations corresponding to dense and loose sands.
