Residual strength of bonded stiffened panels: prediction and experimental verification

This report presents results of residual strength calculations, carried out on cracked panel configurations of various designs and provided with bonded stiffeners. The calculations were carried out using the computer program BOND. The results of these calculations are compared with results of residual strength tests, performed on panels of similar design. It turns out that the calculation results generally compare well but in some cases are slightly unconservative, depending on panel configuration and material combination of sheet and stiffeners. A description of the computer program BOND is given also.
