Abstract

In order to obtain the idealized stress-strain relationships of damaged structural members under tensile and compressive loads, the systematical calculations are performed using the non-linear FE analysis (FEA) code, LS-DYNA. Moreover, the hull girder ultimate strength (HGUS) of damaged hull structures is calculated utilizing the idealized stress-strain relationships of damaged structural members and the simplified calculation program, which is developed by authors and based on the Smith's method. Furthermore, to examine the accuracy of this simplified calculation program, the calculation results are compared with the results obtained from FE analyses.
