本文提出了一种分析具有粘弹性芯层和各向异性面层的夹层层合板的分层微分求积分层有限元模型。单元的刚度矩阵和质量矩阵由Carrera统一公式（CUF）得到。动力学问题在频域中解决，粘弹性频率相关的材料特性的核心。该模型的动态行为与文献中找到的解决方案进行了比较。DQHFE模型被证明是能够提出高精度的结果，使用更少的自由度比低阶计划，如有限元法。(C)2016爱思唯尔有限公司版权所有。
In this paper we present a layerwise differential quadrature hierarchical finite element (DQHFE) model for the analysis of sandwich laminated plates with a viscoelastic core and laminated anisotropic face layers. The stiffness and mass matrices of elements are obtained by Carrera's Unified Formulation (CUF). The dynamic problem is solved in the frequency domain with viscoelastic frequency-dependent material properties for the core. The dynamic behavior of the model is compared with solutions found in literature. The DQHFE model was shown to be able to present highly accurate results using much less degrees of freedom than low order schemes like the finite element method. (C) 2016 Elsevier Ltd.
