摘      要：Peridynamics(PD)is a non-localmechanics theory that overcomes the limitations of classical continuummechanics(CCM)in predicting the initiation and propagation of ***,the calculation efficiency of PDmodels is generally lower than that of the traditional finite elementmethod(FEM).Structural idealization can greatly improve the calculation efficiency of PD models for complex *** study presents a PD shell model based on the micro-beam bond via the homogenization ***,the deformations of each endpoint of themicro-beam bond are calculated through the interpolation ***,the micro-potential energy of the axial,torsional,and bending deformations of the bond can be established from the deformations of ***,the micro moduli of the shellmodel can be obtained via the equivalence principle of strain energy density(SED).In addition,a new fracture criterion based on the SED of the micro-beam bond is adopted for crack *** examples of crack propagation are provided,and the results demonstrate the effectiveness of the proposed PD shell model.
