WebOct 31, 2024 · The most significant advantage of peridynamics is the way to model fracture behaviour. In classical continuum mechanics, precrack surfaces are defined as the domain boundaries. The way to introduce a precrack in peridynamics is to remove all the bond connections that cross the precrack surface. WebTo enhance the calculation accuracy of bond-based peridynamics (BPD), a novel attenuation function is introduced to describe the effect of internal length on nonlocal long-range forces. Furthermore, the expression of the micromodulus function is deduced, and the corresponding fracture criteria are established. The validity and accuracy of the extended …
