WebPeridynamics falls into two fundamental categories viz. bond-based and state-based. In bond-based peridynamics, the interaction between two particles (or material points [15]) is fully defined based on their relative position in the undeformed (base or reference Ω0)and deformed (current Ω) configurations. WebPeridynamics is a recently proposed continuum theory based on a non local approach and formulated with integral equations. The theory is suitable for dealing with crack propagation in solid materials.
