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].

Peridynamics is a new continuum mechanics formulation and it is very suitable to predict fracture initiation and propagation due to its mathematical structure. It is also advantageous to solve moving boundary problems as in the lithiation process considered in this study which is difficult to handle by using traditional techniques

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.

Peridynamic theory has been used to solve a wide range of problems including dynamic fracture analysis [19,20], polycrystals fracture, membranes fracture, fracture of composite materials, modeling

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.
