Bond-based peridynamics: a quantitative study of Mode I

WebJul 2, 2024 · Peridynamics is a rather recent reformulation of nonlocal continuum mechanics [] which tries to unify, and incorporate within a single framework, the mathematical modelling of continuous media, discontinuities, cracks, and particle mechanics [2,3,4,5].In this formulation of a solid mechanics problem, the spatial … 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 … See more Peridynamics is a formulation of continuum mechanics that is oriented toward deformations with discontinuities, especially fractures.
