Peridynamics is a non-local continuum mechanics theory used to model material deformations and fractures at both macro and micro scales. Unlike classical continuum mechanics, which is based on partial differential equations, peridynamics is based on integral equations that describe the interactions between material points in a body. This approach allows for the modeling of material behavior in the presence of discontinuities such as cracks and voids without the need for additional constitutive models. Peridynamics has found applications in a wide range of fields including solid mechanics, fracture mechanics, and materials science. It is particularly useful for modeling complex materials with heterogeneous microstructures, as well as for studying localized deformation and failure mechanisms. The theory has also been used in simulations of impact and penetration events, structural dynamics, and other extreme loading conditions. Overall, peridynamics offers a flexible and computationally efficient framework for studying material behavior under a variety of loading conditions, making it a valuable tool for researchers in the field of mechanics and materials science.
