Sažetak
The purpose of this paper is to examine the weight function method as rapid stress intensity calculation method for damaged stiffened panel. Typical application is the crack propagation assessment when the ship is damaged due to collision or grounding. If the stress distribution is known, as well as the weight function for specific crack geometry it is possible to calculate the stress intensity factor for any non-linear stress distribution. The method is firstly verified on the examples when analytical solutions are available. A new method to account for the effect of stiffener along the crack path using the weight function method is then proposed. The applicability of the weight function method for crack propagation through the damaged stiffened panel is also investigated.
