Nonlocal Peridynamic Modeling and Simulation on Crack Propagation in Concrete Structures

Figure 5

I-II mixed mode crack propagation in concrete slab, with damage defined at the level of pairwise bond locally. (a) No damage occurs with elastic deformation, (b) damage initiation at the crack tip, (c)-(d) damage accumulates, and crack grows along definite orientation, and (e) crack propagates to the boundary.
