Alternatively, viscoplasticity can be modeled by incorporating the rate-dependency in a yield function. 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.

[33] Ha, Y. D. and Bobaru, F., “Studies of Dynamic Crack Propagation and Crack Branching with Peridynamics,” International Journal of Fracture , Vol. 162, 2010, pp. 229-244. 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. Classical continuum mechanics is a special case of peridynamics. Classical continuum mechanincs has been very useful and been utilized to solve many different solid mechanics problems.

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. In this model, viscous effects are added to deviatoric deformations and the bulk re-sponse remains elastic.

, 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. 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 Using the idea of energy equivalence and entropy equivalence, constitutive relations for the peridynamic force states are determined.
