受损船体总纵抗弯能力的半解析估算方法

建立了船体纵向加筋板与横向加筋板对应大变形损伤的损伤分析模型，并采用半解方法对其受损的承载特性进行了讨论，基于受损构件的剩余承载能力分析，给出了受损船体总纵抗弯能力的一近似估算方法，数值算例表明了该方法的有效性。

A Semi-Analytical Method to Evaluate Damage Tolerance of Ship Hull

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.
