The peridynamic microplastic model is used and a three-stage fatigue calculation model is developed to simulate the quasistatic fracture and the fatigue crack growth. The results predicted by the peridynamic models are compared with the experimental ones. Peridynamics is both a superset of continuum mechanics and at the same time it is a new formulation of continuum mechanics.

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].

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 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.

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.

Macek and Silling implemented peridynamics in a commercial finite element analysis code, ABAQUS, using truss elements. The conventional FE mesh is coupled with the peridynamic truss mesh using the embedded element feature available in the finite element analysis code.

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

We propose a new peridynamic formulation with shear deformation for linear elastic solid. The key idea lies in subtracting the rigid body rotation part from the total deformation. Based on the strain energy equivalence between classic local model and non-local model, the bond force vector is derived. 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

Unlike the local elasticity theory, the peridynamics is proposed with no continuum assumption. In this We present a dual-horizon peridynamics (DH-PD) formulation for fracture in granular and rock-like materials.
