AI Technical Summary
Existing methods for damage assessment and repair decision-making in composite material structures are not applicable to complex structures, fail to comprehensively consider the impact of damage location and size on structural failure modes, and lack analysis of the combined effects on strength and stiffness.
Establish an expression relating damage location and size to residual strength rate. Combine the design safety factor and the actual safety factor, predict the residual strength and stiffness of the damaged structure through a numerical simulation model, determine the upper and lower limits of the repair tolerance, and formulate a repair strategy.
It enables rapid assessment and effective repair decisions for composite flat-tail rib structures, improving the efficiency of damage assessment and decision-making, and is applicable to complex structural components.
