Summary
The hybrid structures are subjected to fatigue loading in operation. There is level of loading which doesn't initiate debonding of the glued CFRP plate even for 8e6 loading cycles. Above this loading level the debonding appeared for all tested specimens in the beginning of the test. Using the FEM calculation, the ratio of the strain decreasing due to debonding of 5 mm from the end of CFRP plate was evaluated. This ratio was applied for one test specimen to estimate corresponding number of cycles.
