Computational Modelling of Fracture Propagation in Rocks Using a Coupled Elastic-Plasticity-Damage Model

Figure 12

Crack patterns with variation of homogeneous index . High values of m which represent homogeneous Carrara marble give satisfactory results in comparison with experiments even though all cases show a failure region around the flaw as expected. Experimental result is from Wong [2].

(a) m = 2

(b) m = 4

(c) m = 7

(d) m = 15

(e) No heterogeneity effects

(f) Experiment
