Numerical simulation of cable systems remain delicate due to their geometrical non-linearity and also to their intrinsic unilateral constitutive law. Indeed finite element approaches (if not implemented carefully) fail to predict accurate equilibrium for cable structures. The major issue to be addressed is the ill-conditioning, starting configuration and wrong choice of descent direction during iterative methods. An iterative scheme based on Finite Element Method is presented to overcome this issue, even with large number of elements.

一种稳健有效的电缆数值有限元方法

由于电缆系统的几何非线性及其固有的单边本构法则，电缆系统的数值模拟仍然很微妙。事实上，有限元方法（如果不小心实施）无法预测缆索结构的准确平衡。要解决的主要问题是迭代方法中的病态、起始配置和下降方向的错误选择。提出了一种基于有限元方法的迭代方案来克服这个问题，即使是大量元素。
