This paper deals with the numerical simulation of initiation and propagation of mixed mode
fracture in rocks. A bond-level energy-based peridynamic model is developed by introducing …

Correspondence-based peridynamics (CBPD) is attractive and promising because of its
outstanding ability to employ the traditional constitutive relations for material modeling …

We present an ordinary state-based peridynamic model in 2D and 3D consistent with rate-
independent J2 plasticity with associated flow rule. The new contribution is the capability of …

Peridynamics (PD) is a nonlocal continuum mechanics theory over two scales, where the
macro-scale material responses are built based on the interaction forces among meso-scale …

The bond-based peridynamic (BB-PD) theory is inadequate in describing the four
independent engineering material constants of composite lamina, which results in fixed …

To investigate the influence of the interaction between closed crack surfaces on crack
propagation, a nonlocal friction contact model is proposed for numerical simulation of wing …

In engineering fracture problems, cracks tend to interact with each other rather than exist
singly. In recent years, the phenomenon of multi-cracking has received attention from both …

The pointwise deformation gradient estimated from least squares is essential in material
point-based models, eg, to enrich the constitutive models as well as the failure criteria, and …

An unsolved challenge for successful simulations of rock-like materials is how to describe
the entire fracture process, including the transition from elasto-plastic to strain-softening …

In this study, a new peridynamic interface model is proposed for the imperfect interface
fracture analysis. The peridynamic interface bonds are defined for the imperfect interface …
