mkzp5,"A stochastic multiscale peridynamic model for corrosion-induced fracture","Concrete fracture caused by corrosion of the reinforcing bars plays a key role in accelerating rebar corrosion and causing subsequent structure failure. To better predict this process, we introduce a three-phase stochastic peridynamic model, with the simplest constitutive relation (linear elastic with brittle failure), that avoids the need for explicit concrete microstructure geometry representations. The model links information from the composition at the microscale (phase volume fractions) to the macroscale fracture behavior, while costing the same as a fully homogenized model. We show that a similar peridynamic homogenized model fails in capturing the correct fracture modes/patterns in these problems where the microstructure controls failure behavior. The multiscale model is used to study fracture in reinfo
