WebJun 1, 2010 · In the peridynamic theory, internal forces are expressed through nonlocal interactions between pairs of material points within a continuous body, and damage is a part of the constitutive model. Interfaces between dissimilar materials have their own properties, and damage can propagate when and where it is energetically favorable for it to do so. WebJan 1, 2013 · According to the peridynamic (PD) theory introduced by Silling ( 2000 ), the motion of a body is analyzed by considering the interaction of a material point, { {\mathbf {x}}_ { (k) }} , with the other, possibly infinitely many, material points, { {\mathbf {x}}_ { (j) }}, with (j=1,2,..,\infty ) , in the body.
