This paper combines the finite element (FE) homogenisation and structural assessments to
conduct the multiscale modelling of laminated functionally graded (FG) porous beams made …

When porous materials are subjected to compressive loads, localized failure chains,
commonly termed anticracks, can occur and cause large-scale structural failure. Similar to …

Snow is a highly porous material with properties that may strongly differ depending on the
environmental conditions. On slopes, the layered snowpack may fail and avalanches occur …

A snow slab avalanche releases after failure initiation and crack propagation in a highly
porous weak snow layer buried below a cohesive slab. While our knowledge of crack …

Using the analytical model presented in Part 1 of this two-part paper, a new conceptual
understanding of anticrack nucleation in weak layers is proposed. To obtain a sufficient …

We provide a review of recent works about the Coupled Criterion (CC), originally developed
to assess the initiation of a crack and thus overcome a main limitation of linear elastic …

For the release of a slab avalanche, crack propagation within a weak snowpack layer below
a cohesive snow slab is required. As crack speed measurements can give insight into …

Dry-snow slab avalanches result from crack propagation in a highly porous weak layer
buried within a stratified and metastable snowpack. While our understanding of slab …

For a slab avalanche to release, the system, consisting of a weak layer below a cohesive
slab, must facilitate crack propagation over large distances–a process we call dynamic crack …

Abstract Information on snowpack stability, ie, on the propensity for failure initiation and
crack propagation in a weak layer, is essential for forecasting snow avalanches. To …
