论文摘要
本文开发了一种基于离散化校正粒子强度交换（DC PSE）运算符的新恢复技术。 DC PSE是一种搭配方法，可用于直接在节点点计算衍生物，而不是像在许多基于有限元元素的恢复技术中所做的那样从高斯点投影。所提出的方法确实是无网状的，不需要定义的元素补丁，这通常适用于点云和任意元素拓扑。数值示例表明，所提出的方法是准确且健壮的。
A new recovery technique based on discretization corrected particle strength exchange (DC PSE) operators is developed in this paper. DC PSE is a collocation method that can be used to compute derivatives directly at nodal points, instead of by projection from Gauss points as is done in many finite element-based recovery techniques. The proposed method is truly meshless and does not require patches of elements to be defined, which makes it generally applicable to point clouds and arbitrary element topologies. Numerical examples show that the proposed method is accurate and robust.
