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).

Macek and Silling implemented peridynamics in a commercial finite element analysis code, ABAQUS, using truss elements. Foster, J.T.; Silling, S.A.; Chen, W.W. Viscoplasticity using peridynamics. Int. J. Numer. Methods Eng. 2010, 81, 1242–1258.

The correspondence principle is used to incorporate many classical continuum mechanics models in peridynamics such as rate dependent plasticity or viscoelasticity. 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 current framework is applied to a metallic particulate-reinforced cementitious composite. A coupled thermo-mechanical bond-based peridynamical (TM-BB-PD) method is developed to simulate thermal cracking processes in rocks.

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. It is shown to be stronger in the state-based than in the bond-based version, with multiple wavelengths giving a vanishing phase velocity, one of them longer than the horizon.

This concept has been used to formulate the Consistency model (Wang, 1997; Wang et al., 1997), which appeared to be an efﬁcient and useful tool in the simulation of Lüders bands and Portevin–Le Chatelier effects in metals.

Modelling Cracks in SiC-SiC Cladding Using Peridynamics(A.G. Bamgboye, T.A. Haynes, M. R. Wenman)

The coupled thermo-mechanical model consists of two parts. In the first part, temperature distribution of the system is modeled based on the heat conduction equation.

A uniform discretization scheme is used throughout this study. However, non-uniform discretization can also be possible by using small grid sizes at critical regions such as interfaces and utilizing the “Dual-horizon peridynamics” concept, as introduced by Ren et al. (2016) [46,47].
