WebJun 25, 2024 · Peridynamics is a nonlocal reformulation of the classical solid mechanics and was initiated by Silling ( 2000) mainly to provide consistency in representing a mechanical system whether or not any discontinuity (e.g. cracks) is involved. WebOct 1, 2011 · A non-local, ordinary-state-based, peridynamics viscoelasticity model is developed. In this model, viscous effects are added to deviatoric deformations and the bulk response remains elastic. The model uses internal state variables and is conceptually similar to linearized isotropic viscolelasticity in the local theory.
