摘要

本研究开发并研究了两种新型板弯曲元件。具有13和15自由度的元件分别命名为AT13和AT15。这些三角元素是用半解析的方式表述出来的。为此，采用了带未知参数的基本弹性函数。随后，使用试错过程来确定未识别的常数。并将所得结果与相同自由度的基于位移的三角单元(TUBA13和TUBA15)所得结果进行比较。在本研究中，评估了不同结构的应力和位移响应。在进行了广泛的数值研究后，研究结果清楚地表明了所提出元件的优越性。

Representing capabilities of novel semi-analytical triangular plate elements

Two novel plate-bending elements are developed and investigated in this study. Elements with 13 and 15 degree-of-freedoms are named AT13 and AT15, respectively. These triangular elements are formulated in a semi-analytic way. For this aim, the basic elasticity function is employed with unknown parameters. Subsequently, the trial-and-error procedure is used to determine the unidentified constants. Besides, the achieved results are compared with those obtained by displacement-based triangular elements with the same degrees-of-freedom (TUBA13 and TUBA15). In this research, both stress and displacement responses of diverse structures are assessed. After performing extensive numerical studies, the findings clearly demonstrate the superiorities of the proposed elements.

期刊介绍： The Journal of Strain Analysis for Engineering Design provides a forum for work relating to the measurement and analysis of strain that is appropriate to engineering design and practice. "Since launching in 1965, The Journal of Strain Analysis has been a collegiate effort, dedicated to providing exemplary service to our authors. We welcome contributions related to analytical, experimental, and numerical techniques for the analysis and/or measurement of stress and/or strain, or studies of relevant material properties and failure modes. Our international Editorial Board contains experts in all of these fields and is keen to encourage papers on novel techniques and innovative applications."
