A modified bond-based peridynamic model without limitations on elastic properties

This study proposes a novel Modified Bond-Based PeriDynamic (MBB-PD) model based on the bonds' classification. classification of bonds is performed basis equivalent hypothetical local strains and falls into three categories horizontal normal, vertical shear bonds. While classical PD (BB-PD) considers only stretch bonds, all components are taken account in proposed model.A imaginary element considered around each bond to estimate true bond. The constitutive relations derived from equating strain energies deformations Classical Continuum Mechanics (CCM) for generalized combined loading condition. A critical criterion angle predict failure normal respectively.It also shown that, unlike BB-PD, does not impose any limitations value Poisson's ratio. verified by investigating some intact plane stress problems under mechanical thermal loadings. Moreover, deformation damage contours corresponding stress-strain responses presented different with pre-existing defects validated eXtended Finite Element method's (XFEM) analysis.
