Identification of the crushing behavior of brittle foam ...

 · Brittle fracture, as a result of the weakest link mechanism (Pierce, 1926, Weibull, 1952, Freudenthal,), is known to display systematic size effects. In the present case, because the elementary phenomenon is the brittle fracture of walls between pores, one may wonder whether pore collapse shows such a size effect.

Tracking time with ricequakes in partially soaked brittle ...

When brittle porous media interact with chemically active fluids, they may suddenly crumble. This has reportedly triggered the collapse of rockfill dams, sinkholes, and ice shelves. To study this problem, we use a surrogate experiment for the effect of fluid on rocks and ice involving a column of puffed rice partially soaked in a reservoir of liquid under constant pressure.
