Abstract

In order to obtain the non-linear average stress-average strain relationships (σ-ϵ curves) of damaged structural members under both tensile and compressive loads, the systematical calculations are performed using the non-linear FE analysis (FEA) code, LS-DYNA, and the idealized σ-ϵ curves of damaged structural members are estimated from FEA results. In addition, by introducing the idealized σ-ϵ curves of damaged structural members to the simplified calculation program, which is developed by authors and based on the Smith's method, the residual ultimate strength of damaged hull structures is calculated. The residual ultimate strength of damaged hull structures is also calculated utilizing FEA, the calculation results by the simplified calculation program are compared with the results obtained from FE analyses so as to examine the accuracy of simplified calculation method.
