Experimental Study on Residual Strength of Panels with Multiple Site Damage

Abstract:

The fatigue test of typical bolt-hole panels with five open holes in a line and the residual strength test of the panels with multiple site crack (MSD) were carried out. The crack initiation life of the test panels and the residual strength of the panels with different MSD crack sizes were obtained by the tests. The application of the net section yield criterion in the determination of residual strength of the panel containing multiple site damage was studied by comparing the calculated results with the test results. The conclusion is that the criterion meets the engineering accuracy requirement in the case of smaller MSD cracked area or smaller MSD crack sizes.
