The peridynamic theory is based on integral equations, in contrast with the classical theory of continuum mechanics, which is based on partial differential equations. Since partial derivatives do not exist on crack surfaces and other singularities, the classical equations of continuum mechanics cannot be applied directly when such features are present in a deformation. The integral equation… WebMar 1, 2024 · This theory reinforces the relations between peridynamics and classical mechanics and offers an effective method to adopt constitutive models.
