Fatigue crack growth test for cracked metallic plate of LY12CZ aluminum alloy repaired with adhesive bonding Carbon/epoxy composite patch is conducted to validate the crack growth behaviour of crack patching.The main fatigue failure modes observed in the test are crack growth and adhesive debonding.The crack length and debonding area are measured with different numbers of cycles.The nonlinear 3D finite element model considering adhesive debonding and crack growth are developed.The experimental and analytical results are in good agreement with each other.
