在工程科学中,薄壁结构破坏的分析和可靠性评估非常重要,其重点是薄壁结构中如钢管和压力容器的动态数值分析。由于无网格方法具有更高阶的连续性,并且有可能以更简单的方式来模拟结构的破坏,所以本文中将其代替有限元法,对结构进行分析。因此在本文中,一旦结构的发展与其破坏曲线吻合,相邻的结点之间的连接也将马上移除。这种无网格方法最大的优势就在于它的简单化与可靠性。 In engineering science, the analysis and reliability assessment of thin-walled structures is very important. The focus is on the dynamic numerical analysis of thin-walled structures such as steel tubes and pressure vessels. Because the meshless method has higher order continuity and it is possible to simulate the structural failure in a simpler way, this paper will replace the finite element method to analyze the structure. Therefore, in this paper, once the structural development coincides with the destruction curve, the connection between adjacent nodes will be removed immediately. The biggest advantage of this meshless approach is its simplicity and reliability.
