The peridynamics theory is a reformulation of nonlocal continuum mechanics that incorporates material particle interactions at finite distances into the equation of motion. MODELLING OF STRESS-CORROSION CRACKING BY USING PERIDYNAMICS Dennj De Meo1, 1Cagan Diyaroglu1, Ning Zhu , Erkan Oterkus1, *, M. Amir Siddiq2 1 Department of Naval Architecture, Ocean and Marine Engineering, University of Strathclyde, Glasgow, Lanarkshire, G4 0LZ, UK 2 School of Engineering, University of Aberdeen, Aberdeen, AB24 3UE, UK ABSTRACT We model the interaction of particle beds with a plate due to gravity, where the particle shapes are allowed to be non-convex. The intra-particle force is mo Peridynamics is a theory of continuum mechanics employing a nonlocal model that can simulate fractures and discontinuities (Askari et al. J Phys 125:012---078, 2008; Silling J Mech Phys Solids 48(1 are inherently represented by defining a bond relationship between particles using a constitutive model. Furthermore, the bond relationship between dissimilar material phases is inherently integrated in the peridynamic method. Two methods are primarily used: bond-based peridynamics (BBPD) [26,27] and micro-polar peridynamics (MPPD) [28,29].
Many attempts have been made to Using the idea of energy equivalence and entropy equivalence, constitutive relations for the peridynamic force states are determined. The proposed peridynamic visco-plastic-damage model may be thought as a non-trivial extension of the recently developed peridynamic visco-plasticity model (Rahaman et al.,2017).
A new damage rule of maximal deviatoric bond strain for elastic brittle fracture is proposed in order to account for both the tensile damage and shear damage. 2D and 3D numerical examples are Peridynamics is a nonlocal extension of classical W.W. Chen, Viscoplasticity Using Peridynamics, Sandia National Laboratories Technical Report SAND2008-7835, 2008 Similar to the classical nonlocal models, the peridynamic dispersion of elastic waves occurs for high frequencies.

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. Foster et al.

Peridynamics is a nonlocal extension of classical solid mechanics that permits discontinuous solutions “In peridynamics, cracks are part of the solution, not part of the problem ” Peridynamic equation of motion (integral, nonlocal) u(x,t) f(u' u,x x)dV b(x,t) not part of the problem. The peridynamic theory, which is a nonlocal continuum theory, provides a suitable framework for modeling dynamic problems involving fracture.
