The assumptions in the original peridynamic theory resulted in severe restrictions on the types of material response The U.S. Department of Energy's Office of Scientific and Technical Information 2019-05-01 · Merits of using peridynamics. Our PD based formulation of visco-plastic-damage extends the realm of application of the PD approach to problems involving very high strain-rates, fracture and fragmentation. The computational implementation of fracture and fragmentation under high rates of loading is simple and effective with a PD based scheme. 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.

For example, state-based formulations of viscoplasticity models [13] and ductile damage models for met-als [14, 15] have recently been proposed and e ectively used in simulations based on particle discretizations. This novel method of coupling peridynamics with a highly efficient mesh in the hydraulic fracture model will be fully detailed in this dissertation.

2018-10-11 · Peridynamics (PD) is a novel continuum mechanics theory established by Stewart Silling in 2000. The roots of PD can be traced back to the early works of Gabrio Piola according to dell’Isola et al.
