3 Studying Wear and Friction in Carbon Thin Films with Peridynamic Chapter 6 : Here, a new peridynamic model is proposed to model viscoplastic behavior.

Authors: Foster, John T. Publication Date: Tue Dec 01 00:00:00 EST 2009 Research Org.: Sandia National Lab. (SNL-CA), Livermore, CA (United States) Viscoplasticity is usually modeled in three-dimensions using overstress models of the Perzyna or Duvaut-Lions types. In these models, the stress is allowed to increase beyond the rate-independent yield surface upon application of a load and then allowed to relax back to the yield surface over time. 2012-10-15 · Foster et al., studied viscoplasticity and the failure criterion for peridynamic states.

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.

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. The conventional FE mesh is coupled with the peridynamic truss mesh using the embedded element feature available in the finite element analysis code. Peridynamics is a nonlocal extension of classical W.W. Chen, Viscoplasticity Using Peridynamics, Sandia National Laboratories Technical Report SAND2008-7835, 2008 Viscoplasticity using peridynamics.

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. In the second part, the mechanical deformation caused by temperature change is calculated to Foster JT, Silling SA, Chen WW (2010) Viscoplasticity using peridynamics.

In this work, we report a computational study on Peridynamics modeling and simulation of soil fragmentation under buried explosive loads. We have implemented several geomaterial models of soil in the state-based Peridynamics formulation, which can take into account of the effects of strain softening, viscoplasticity, and porosity of soil.

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).

20 Jan 2021 “Viscoplasticity using peridynamics.” (with S.A. Silling and W. Chen) 10th US National Congress on Computational Mechanics. July 2009. Student The peridynamic theory has been successfully applied to damage analysis of viscoplastic materials ([29]; [30]), dynamic fracture and crack branching in glass Peridynamics is a reformulated nonlocal elasticity theory. 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.
