ABSTRACT = {Classical continuum mechanics which leads to a local continuum model,
encounters challenges when the discontinuity appears, while peridynamics that falls into
the category of nonlocal continuum mechanics suffers from a high computational cost. A
hybrid model coupling classical continuum mechanics with peridynamics can avoid both
disadvantages. This paper describes the hybrid model and its adaptive coupling approach
which dynamically updates the coupling domains according to crack propagations for
brittle materials. Then this hybrid local/nonlocal continuum model is applied to fracture
simulation. Some numerical examples like a plate with a hole, Brazilian disk, notched
plate and beam, are performed for verification and validation. In addition, a peridynamic
software is introduced, which was recently developed for the simulation of the hybrid
local/nonlocal continuum model.},
