摘要

为了精确、高效地分析复杂复合材料的电磁特性，提出了一种富界面广义有限元方法。IGFEM在不使用符合材料界面的网格的情况下，丰富了材料界面处的解空间，以捕捉场及其导数的不连续。通过两个验证算例和一个工程问题，分别验证了IGFEM的准确性及其在模拟具有复杂和随机分布内部结构的复合材料方面的潜力。

An interface-enriched generalized FEM for EM analysis of composites with nonconformal meshes

An interface-enriched generalized finite-element method (IGFEM) is presented for accurate and efficient electromagnetic analysis of complex composite materials. Without using meshes that conform to the material interfaces, the IGFEM enriches the solution space at the material interfaces to capture the discontinuities of the field and its derivatives. Two verification examples and one engineering problem are provided to respectively demonstrate the accuracy of the IGFEM and its potential in modeling composites with intricate and randomly distributed internal structures.
