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.
Unlike the partial differential equations of the standard theory, the basic equations of peridynamics are applicable even when cracks and other singularities appear in the deformation field.
The roots of PD can be traced back to the early works of Gabrio Piola according to dell’Isola et al. [22] Oterkus, S., 2017, “Thermo-Oxidative Damage Evolution in a Composite Lamina by using Peridynamics” Euromech Colloquium 579 Generalized and Microstructured Continua: New Ideas in Modelling and/or Applications to Structures with nearly Inextensible Fibers 3-8 April 2017, Arpino, Italy. The peridynamics theory is a reformulation of nonlocal continuum mechanics that incorporates material particle interactions at finite distances into the equation of motion.

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. In contrast to discrete crack methods such as XFEM 27 May 2016 At the origins and in the vanguard of peridynamics, [30] Forest, S. Micromorphic approach for gradient elasticity, viscoplasticity, and damage. state-based peridynamics is in turn of two types: ordinary and non-ordinary.

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. A new damage rule of maximal deviatoric bond strain for elastic brittle fracture is proposed in order to account for both the tensile damage and shear damage.
