Abstract

This work presents a three-dimensional (3D) numerical analysis of multi-layered laminated plates in which selected layers may be made of functionally graded material (FGM), in which the Young’s modulus may change along the thickness as a consequence of a continuous and graded mixture of two materials. For the analysis, the method, known as FEM23, is applied, which uses a two-dimensional (2D) mesh, yet enables obtaining full 3D results for the layered structure. In FEM23, the layered structure may be a combination of thin and thick layers made of materials with significantly different properties. This paper presents two examples comparing the results to other numerical or analytical solutions. The examples confirm the correctness and flexibility of FEM23 for laminated plates with functionally graded layers.

基于二维数值模型的功能梯度层合板三维分析

这项工作提出了多层叠合板的三维(3D)数值分析，其中选定的层可能由功能梯度材料(FGM)制成，其中杨氏模量可能随着厚度的变化而变化，这是两种材料连续和梯度混合的结果。在分析中，采用了称为FEM23的方法，该方法使用二维(2D)网格，但可以获得分层结构的完整3D结果。在FEM23中，层状结构可能是由性能差异显著的材料组成的薄层和厚层的组合。文中给出了两个算例，将结果与其他数值解或解析解进行了比较。算例验证了FEM23对功能梯度层合板的正确性和灵活性。

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
