DOI: 10.1016/j.ijimpeng.2016.09.003
Abstract: Abstract Peridynamics is a new nonlocal theory that provides the ability to represent displacement discontinuities in a continuum body without explicitly modeling the crack surface. In this paper, an explicit dynamics implementation of the bond-based… read more here.
