The Application of Nonordinary, State-Based Peridynamic Theory on the Damage Process of the Rock-Like Materials

Abstract EN

Peridynamics has a great advantage over modeling the damage process of rock-like materials, which is assumed to be in a continuum interaction with each other across a finite distance.

In the paper, an approach to incorporate classical elastic damage model in the nonordinary, state-based peridynamics is introduced.

This method can model the dynamic damage process and stress change of rock-like materials.

Then two instances about three-point bend experiment are simulated in the rock-like materials.

Finally the conclusions are drawn that numerical results are close to the experimental results.

So the method has a great predictable value in the geotechnical engineering.
