Abstract Peridynamics (PD) is a non-local mechanics theory that overcomes the limitations of classical continuum mechanics (CCM) in predicting the initiation and propagation of cracks. However, the calculation efficiency of PD models is
generally lower than that of the traditional finite element method (FEM). Structural idealization can greatly improve
the calculation efficiency of PD models for complex structures. This study presents a PD shell model based on the
micro-beam bond via the homogenization assumption. First, the deformations of each endpoint of the micro-beam
bond are calculated through the interpolation method. Second, the micro-potential energy of the axial, torsional,
and bending deformations… More >
