A number of methods for hull collapse analysis have been developed, taking into account buckling and yielding, but the importance of necking and ductile-fracture behavior has been disregarded. In this paper, a simplifiedmodel for steel members is formulated for modeling necking and ductile-fracture behavior. The model is incorporated into the previous ISUM units which have been developed, considering buckling and yielding. Application toanalysis of the progressive collapse behavior for a 1/3-scale frigate test hull in the sagging condition is demonstrated, and tensile behavior of local members on hull collapse is discussed.
