“…In mean-field theories of amorphous matter, [108,7,6,62,156,158,65,194,140,43,157], the amplitude of the stress redistribution, along with the distribution from which the stress changes are drawn, plays an important role. In the mean-field approaches, and even other elasto-plastic models constructed in real-space, the amplitude is usually taken as a purely ad-hoc parameter and rarely motivated physically.…”
