Dokken等人（2013）[6]最近提出的局部细化B样条（表示为LR B样条）可能有潜力成为等几何分析的框架，以实现未来的互操作计算机辅助设计和有限元分析。在本文中，我们提出了局部细化策略的自适应等几何分析，使用LR B样条，并研究其性能进行数值测试，在著名的基准情况下。LR B样条背后的理论没有详细介绍，但主要的概念成分解释和说明了一些例子。
The recently proposed locally refined B-splines, denoted LR B-splines, by Dokken et al. (2013) [6] may have the potential to be a framework for isogeometric analysis to enable future interoperable computer aided design and finite element analysis. In this paper, we propose local refinement strategies for adaptive isogeometric analysis using LR B-splines and investigate its performance by doing numerical tests on well known benchmark cases. The theory behind LR B-spline is not presented in full details, but the main conceptual ingredients are explained and illustrated by a number of examples.
