A critical strength criterion for stiffened thin plates, such as ship hulls, is their ability to resist buckling. A ship is continuously supported by the buoyant volume of the hull, which changes under wave action and causes varying magnitudes of bending moment resisted by the longitudinally continuous structure within the hull girder. In the present work, a set of finite element analyzes (FEA) was carried out, using the commercial finite element package ANSYS APDL to reproduce the mechanical behavior of cracked stiffened panels when subjected to longitudinal compression. The objectives were to evaluate the buckling behavior and the stress-displacement relationship of the analyzed structures. The effect of crack size and the evolution of the stress intensity factor in three buckling analyzes were examined in this present work. Three positions of the stiffeners were considered and tested. Initial geometric imperfections based on a deformation mode were scaled and fed into physical and geometric incremental nonlinear analysis.
