In this work, a nonlocal peridynamics–smoothed particle hydrodynamics (SPH) coupling formulation has been developed and implemented to simulate soil fragmentation induced by buried explosions. 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.

The peridynamics theory is a reformulation of nonlocal continuum mechanics that incorporates material particle interactions at finite distances into the equation of motion.

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.

In this work, a nonlocal peridynamics---smoothed particle hydrodynamics (SPH) coupling formulation has been developed and implemented to simulate soil fragmentation induced by buried explosions.
