Continuum limit of amorphous elastic bodies II: Linear response to a point source force
Continuum limit of amorphous elastic bodies II: Linear response to a point source force
The linear response of two-dimensional amorphous elastic bodies to an external delta force is determined in analogy with recent experiments on granular aggregates. For the generated forces, stress, and displacement fields, we find strong relative fluctuations of order 1 close to the source, which, however, average out readily to the …
