Growth of gas-filled penny-shaped cracks in decompressed hydrogels

Y Zhang, MA Etzold, A Lefauve - Soft Matter, 2021 - pubs.rsc.org
We report that the decompression of soft brittle materials can lead to the growth of internal
gas-filled cracks. These cracks are oblate spheroids ('penny shape'), whose major radius …
