But because of variety of ship types, complexity of ship structure, and relationship to strongly non-linear factors of material and geometry, the calculation of ship hull's ultimate strength becomes a complicated mechanical problem.
然而,由于船舶类型的多样性、船体结构的复杂性,以及涉及到材料和几何的非线性因素,同时还必须考虑多种因素的影响,使得船体极限强度计算这一力学问题变得十分复杂。
