本文采用美国船级社的非线性有限元程序USAS，对四种船体构型的总纵极限强度进行了计算。每个分析中包括屈曲、后屈曲和塑性的影响。由于分析方法的通用性，这些效应的相互作用和船舶船体的各种结构部件的相互作用以统一的、严格的方式被考虑。讨论其他的，更有限的，极限强度分析方法的地方的观点。本文的一个重要方面是一个广泛的治疗有限元建模过程中所需的保持精度，但保持成本最低。极限强度的敏感性的研究结果，在几个参数的变化，包括屈服应力，厚度和缺陷的大小，也提出了。
The American Bureau of Shipping's nonlinear finite-element program USAS is used to evaluate the longitudinal ultimate strength of four ship hull configurations. Included in each analysis are the effects of buckling, post-buckling, and plasticity. The interaction of these effects and the interaction of the various structural components of the ship hull are accounted for in a unified, rigorous manner owing to the generality of the analysis method. Discussion of other, more limited, ultimate-strength analysis methods places the approach in perspective. An important aspect of this paper is an extensive treatment of the finite-element modeling procedures necessary for maintaining accuracy, yet keeping cost to a minimum. Results of a study on the sensitivity of the ultimate strength to variations in several parameters, including yield stress, thickness and magnitude of imperfections, are also presented.
