Present paper is an analytical work on a patch repair problem. An exact solution is obtained for double lap patch-repaired circular plates with debondings between the two patches and the base plate subjected to a uniform axisymmetric radial displacement, where no bending deformation is considered. The explicit solution based on a simplified plate model excellently agreed with a finite element solution. Through a parametrical study on the strain distribution and the energy release rates for the debondings based on the analytical solution, various general rules on the design of the patch repairs are elaborated.
