| Abstract: | In this paper the damage models of ship structures are presented and tested. Two typical kinds of stiffened plates for ship structures, namely the longitudinally and the transversally stiffened plates, are discussed respectively. Based on the discussion of residual strength of damaged ship structures with elasto-plastic deformation, a semi-analytical method is presented in this paper to evaluate the damage tolerance of ship hull. Numerical examples have been implemented to illustrate the validity of the presented method. |
