Özet

Accurate deflection curve of the plastically damaged deflection curve and residual stress distribution are essential and play an important role in residual strength calculation. Unfortunately, all these demands need a lot of modelling and CPU time. This study represents a new type of very simple methodology that models initial geometric imperfection of damaged stiffeners by employing curvature values. Thus, it will be possible to predict the reduction in ultimate strength due to the damages of the structure. The results will be compared with the FEM commercial program, ANSYS.
