摘要
介绍了海洋平台水下结构累积损伤失效路径的动态搜寻方法,重点阐述了增量载荷法,分支限界法和β-解链法,及对方法的某些合理改进,最后指出了各种方法的优缺点,并提出了目前解决失效路径动态搜寻所存在的一些关键问题。
The methods for dynamically selecting main invalid routes being caused by accumulating damage of the undersea part of offshore platforms are summarized. The incremental loading method and the branch-and-bound method the β- unzipping method are introduced. Based on these methods, some tea sonable improvements to these methods are drawn up by some other scholars. The advantage and disadvantage of these methods are pointed out. Some key conclusions are acquired.
