For example, waterfall, incremental, or iterative models can be created with the same overlapping method content.
例如，瀑布，递增，或是迭代模型可以用相同的重叠方法内容建立。

In this paper, facing the convergent problem of plastic forming using large incremental step, we deduced the iterative formula used in analysis of elastic-plastic plate forming finite element method.
Numerical results are performed with two-level approximations, which demonstrate that the incremental unknowns method when combined with some iterative methods is very efficient.
