摘要：
Aiming at the computational efficiency issue associated with the peridynamics method，a hybrid modeling strategy that combines the peridynamics method with the finite element method was proposed．By setting up peridynamic domains and finite element domains in the fractured and non-fractured regions，respectively，and utilizing interface elements and virtual boundary layers to connect these domains，the hybrid modeling was realized． The virtual boundary layer，functioning as the peridynamic computational domain's outer boundary，transmitted deformation feedback from the finite element domain to the peridynamic domain． The displacement field information was updated and transmitted by the finite element computational domain． After validation through tensile testing of a two-dimensional pre-cracked plate，it is found that the maximum calculation error of the hybrid model compared to that of the single peridynamics method is 2.6%，yet its computational efficiency is improved by 24.0%，indicating favorable application prospects． © 2024 Huazhong University of Science and Technology.
