My main research interest
Development of peridynamics and its applications.
What is peridynamics?
Peridynamics is a mathematical theory of mechanics that extends classical continuum mechanics to include discrete particles and growing cracks. Its applications include:
- Unguided modeling of fracture in metals and composites.
- Transition from continuous damage to fracture.
- Modeling of long-range forces within a continuous body.
- Atomistic to continuum coupling in a consistent mathematical framework.
