Axisymmetric Stress State of Adhesive Joint of a Circular Patch with a Plate Weakened by a Circular Cut-out

Adhesive lap joints are widely used in modern structures. Known analytical mathematical models of the stress state describe straight beams or cylindrical coaxial pipes. It is assumed that these structures depends on only one coordinate. The study plates with defects, which reinforced by patches, most cases requires use at least two-dimensional models. In this work, it shown axial symmetry plate, cut-out, patch, and applied load makes possible to reduce problem a one-dimensional polar coordinate system. An adhesive joint circular considered for first time. stress-strain structure described an form. Comparison results calculating finite element modelling showed good adequacy proposed model.
