19 FAILURE MODES - is the bending resistance of the shell or of the flange, considering the M-N and M-V interaction respectively. It is iteratively derived from: = = = = = flange , yd 2 2 flange , yd U flange , pl 2 flange , pl flange , V , pl shell , yd 2 2 shell , yd U shell , pl 2 shell , pl shell , N , pl 3 , pl f 4 t c f t c F 1 M V V 1 M f 4 s c f s c F 1 M N N 1 M min M 3 , pl M yd 2 2 , pl f 4 t ' c ' M = - is the reduced bending resistance of the flange at the bolt axis yd 2 2 , pl f 4 t c M = - is the full bending resistance of the flange
