Abstract

In this article, a hybrid FEM-MESHLESS method for dynamic analysis of homogeneous and inhomogeneous structures is developed. This hybrid method has already been shown by El Kadmiri et al (2021, 2022, 2024) for static analysis of homogeneous and inhomogeneous structures. To verify the proposed method for studying the dynamic response of homogeneous and inhomogeneous structures, a study based on small deformations theory is presented by comparison with the results of finite element method and those of analytical solutions. In addition, numerical tests are carried out to demonstrate the reliability and performance of the proposed algorithm by establishing a convergence study using regular and irregular discretization schemes.

均匀与非均匀结构动力分析的混合有限元-无网格方法

本文提出了一种用于均质和非均质结构动力分析的有限元-无网格混合方法。El Kadmiri等人（2021,2022,2024）已经证明了这种混合方法用于均匀和非均匀结构的静力分析。为了验证本文提出的研究均质和非均质结构动力响应的方法，通过与有限元法和解析解结果的比较，提出了基于小变形理论的研究方法。此外，通过建立正则和不规则离散化方案的收敛性研究，进行了数值试验，以证明该算法的可靠性和性能。

期刊介绍： This journal is specifically dedicated to the dissemination of the latest developments of new engineering analysis techniques using boundary elements and other mesh reduction methods. Boundary element (BEM) and mesh reduction methods (MRM) are very active areas of research with the techniques being applied to solve increasingly complex problems. The journal stresses the importance of these applications as well as their computational aspects, reliability and robustness. The main criteria for publication will be the originality of the work being reported, its potential usefulness and applications of the methods to new fields. In addition to regular issues, the journal publishes a series of special issues dealing with specific areas of current research. The journal has, for many years, provided a channel of communication between academics and industrial researchers working in mesh reduction methods Fields Covered: • Boundary Element Methods (BEM) • Mesh Reduction Methods (MRM) • Meshless Methods • Integral Equations • Applications of BEM/MRM in Engineering • Numerical Methods related to BEM/MRM • Computational Techniques • Combination of Different Methods • Advanced Formulations.
