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.

PD has been attractive to researchers as it is a non-local formulation in an integral form, unlike the local differential form of classical continuum mechanics. 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.

Viscoplasticity using peridynamics

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.
