Abstract

The fracture analysis of cracked thick plates repaired with adhesively bonded composite patches using a boundary element formulation is presented. The shear deformable cracked isotropic plate was modeled using the dual boundary method. In order to model the repair, a three parameter boundary element formulation was established. This formulation is based on Kirchhoff's theory for symmetric layer composite plates and considers the transversal deflection and two in-plane rotations. Interaction forces and moments between the cracked plate and the composite repair were modeled as distributed loading, and discretized using continuous and semi-discontinuous domain cells. Coupling equations, based on kinematic compatibility and equilibrium considerations for the adhesive, were established. In-plane shear-deformable adhesive model without transversal stiffness was considered in order to modeling the mechanical response of the adhesive. Stress intensity factors in the isotropic Reissner's plate were calculated using crack surface displacements extrapolation. Test problems considering circular composite repair are presented.
