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.
