Athermal quasistatic cavitation in amorphous solids: Effect of random pinning
UA Dattani, S Karmakar, P Chaudhuri - The Journal of Chemical …, 2023 - pubs.aip.org
Amorphous solids are known to fail catastrophically via fracture, and cavitation at nano-
metric scales is known to play a significant role in such a failure process. Micro-alloying via …
