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. 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.

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 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). Viscoelasticity Model for Peridynamics John A. Mitchell Sandia National Laboratories 1515 Eubank SE Albuquerque, NM 87185 Abstract A non-local, ordinary-state-based, peridynamics viscoelasticity model is developed.
Foster et al. , studied viscoplasticity and the failure criterion for peridynamic states. Compared with FEM, peridynamics is computationally expensive. Macek and Silling implemented peridynamics in a commercial finite element analysis code, ABAQUS, using truss elements.

What is Peridynamics? 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. Prior research has focused mostly on the continuum, bulk response, neglecting any localized material failure, of granular materials. A systematic investigation of the effects of grain fracture and frictional
The term "peridynamics," a noun, is a shortened form of the phrase peridynamic model of solid mechanics. Pairwise force functions. Using the abbreviated notation = (,) and ′ = (′,) Newton's third law places the following restriction on :

220: 2010: Based upon the integrodifferential equations, peridynamics enables predicting the complex fracture phenomena such as spontaneous crack nucleation and crack branching, curving, and arrest. In this paper, the bond-based peridynamic approach is used to study the impact damage in a beam with an offset notch, which is widely used to investigate the mixed I-II crack propagation in brittle materials. 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.
