Ductile and brittle yielding of athermal amorphous solids: A mean-field paradigm beyond the random-field Ising model
JT Parley, P Sollich - Physical Review E, 2024 - APS
Amorphous solids can yield in either a ductile or brittle manner under strain: plastic
deformation can set in gradually, or abruptly through a macroscopic stress drop. Developing …
