Peridynamics is both a superset of continuum mechanics and at the same time it is a new formulation of continuum mechanics. Classical continuum mechanics is a special case of peridynamics. Classical continuum mechanincs has been very useful and been utilized to solve many different solid mechanics problems.

The roots of PD can be traced back to the early works of Gabrio Piola according to dell’Isola et al. 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.

J Phys 125:012---078, 2008; Silling J Mech Phys Solids 48(1 are inherently represented by deﬁning a bond relationship between particles using a constitutive model. Furthermore, the bond relationship between dissimilar material phases is inherently integrated in the peridynamic method. Two methods are primarily used: bond-based peridynamics (BBPD) [26,27] and micro-polar peridynamics (MPPD) [28,29].

19–43. [Google Scholar] What is Peridynamics? Peridynamics is a nonlocal extension of classical solid mechanics that permits discontinuous solutions “In peridynamics, cracks are part of the solution, not part of the problem ” Peridynamic equation of motion (integral, nonlocal) u(x,t) f(u' u,x x)dV b(x,t) not part of the problem. The peridynamic theory, which is a nonlocal continuum theory, provides a suitable framework for modeling dynamic problems involving fracture.
