WebIn simulating discontinuities such as cracks, a derivative-free continuum theory – peridynamics, to wit – has an advantage in that the integro-differential balance laws work even with discontinuities. It does not need the special measures required with continuum models using partial differential equations (PDEs) for simulating cracks. WebAug 1, 2024 · Peridynamics evaluates the forces on material points in an integral form, which is different from mesh-based methods such as finite element or finite difference methods. On the other hand, the presence of discontinuity does not increase complexity, and it may provide some advantages in modeling and simulation e.g. [42].
