“…Recent works based on such bilinear/trilinear behavior of PD bonds focused on aspects of crack nucleation from a material stability point of view and crack propagation [10][11][12][13][14]. Reference [10] presented a bilinear law for PD bond force-strain curve, alongside the original linear bond force-strain curve presented in [15] for the PMB model.…”

“…The other parameter in the bilinear model is then evaluated from the critical fracture energy (similar to the calculation of the critical bond strength in the PMB model in [9]). A PD model with a trilinear bond force-strain relationship for quasi-brittle behavior was proposed in [14] with the softening part of the bond force-strain curve being calibrated to the corresponding experimental softening curve. Note that PD models with bilinear force-bond strain behavior have also been used to simulate elasto-plastictype behavior ( [16,17]).…”

“…A formulation of pressure-dependent PD plasticity model was shown to work well for compression, impact, and spallation of concrete structures [51]. The trilinear peridynamic model introduced in [52] has shown good results in terms of the load-CMOD curves for threepoint-bending tests. This model, however, being a homogenized one, cannot capture the rough and tortuous crack trajectories.…”

Concrete fracture caused by corrosion of reinforcing bars may cause subsequent structure failure. To better predict this process, we introduce a partially-homogenized stochastic peridynamic model with the simplest constitutive relation (linear elastic with brittle failure). The model links microscale information (phase volume fractions of mortar, aggregates, interfaces) to macroscale fracture behavior, while costing the same as a fully homogenized model. We show, and explain why a fully-homogenized peridynamic model fails to capture the correct concrete fracture modes/patterns, while the new model succeeds. The multiscale model predicts the evolution of fracture in reinforced concrete caused by corrosion products expansion in samples with a single or multiple rebars. Non-uniform expansion of corrosion products is enforced here as preset, incremental radial displacements. The computed fracture patterns and the order in which various cracks develop match what is seen in experiments. The model's robustness is tested under different stochastic realizations and discretization grid types.

“…Therefore, researches on crack propagation behaviours in concrete is of great significance in engineering practice. A series of research has been initiated to improve the understanding of failure mechanism in concrete, especially from the perspective of fracture mechanics . In order to assess the failure, the concept of energy release rate (ERR or G ) or stress intensity factor (SIF or K ) in fracture mechanics are generally introduced, predicted, and compared with its critical value G c or K c ; fracture tests are necessitated for these experimental values.…”

A numerical model is proposed to simulate crack propagation at concrete matrix‐aggregate interface. One single aggregate surrounded by concrete matrix is taken to demonstrate the behaviours of crack penetration into concrete matrix and crack growth along the interface. Influences of side‐edge constraint, aggregate direction, and interface fracture energy on the crack propagation behaviours are respectively investigated. The results show that, tensile constraint on the side edge, a smaller angle between tensile axis and aggregate, and higher fracture energy lead to a higher rupture strength of the interface. Once the interface crack starts to grow, it propagates to the two ends of aggregate major axis drastically and further penetrates into the matrix. Nevertheless, these factors have no appreciable influence on crack propagation path. By mapping interface crack into major axis, ordinary crack is generated. Using the above simplification, modelling of multiple crack propagation in concrete is efficiently achieved.
