Asymptotic Crack-tip Fields in an Anisotropic Plate Subjected to Bending, Twisting Moments and Transverse Shear Loads by F.G. Yuan; S. Yang is a Engineering article available to read on EtoBox.
Asymptotic crack-tip ®elds, including the eect of transverse shear deformation, in an anisotropic plate under bending, twisting moments and transverse shear loads are presented. By utilizing the Hellinger±Reissner variational principle, the equilibrium equations and generalized strain/stress relations for anisotropic Reissner plate theory are obtained. Assuming the displacement and stress resultant are in a separation-of-variable form, it is found that, for the ®rst two order terms of the asymptotic solution, the equations governing crack-tip ®elds of anisotropic plate bending are analogous to those governing plane stress and anti-plane deformation of anisotropic elasticity. Thus the Stroh formalism can be used to characterize the crack-tip ®elds of the anisotropic plate up to the second-order term and the energy release rate can be expressed in a very compact form in terms of stress intensity factors and the Barnett±Lothe tensor L. The ®rst three order terms of the crack-tip displacement and stress ®elds including the ``Tstresses'' in bending and transverse shear are presented. The displacement and stress ®elds near crack tips in isotropic plates up to the second order are also pr
