Abstract

AbstractThe dynamic thermomechanical analysis on stiffened composite plates with damages are investigated in this article based on the extended layerwise method (XLWM) and three-dimensional finite elements method; a thermomechanical extended-layerwise/Solid-element method (TELW/SE) is established. In TELW/SE, the thermomechanical extended-layerwise method (TELW) and thermomechanical three-dimensional solid elements are used to simulate plate and stiffeners, respectively. The final governing equations are assembled by using the interface conditions to ensure the compatibility of displacements and temperature, together with the internal force equilibrium. Several typical damages in stiffened composite plates can be described accurately in the proposed method, such as delamination, transverse crack and stiffener/plate interface debonding.Keywords: Delaminationdynamic thermomechanical analysisextended layerwise methodinterface debondingstiffened composite platestransverse crack Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the Natural Science Foundations of China (12072364, U1933102) and Fundamental Research Funds for the Central Universities (3122019074).

带损伤的加筋复合材料板动态热力学分析

摘要基于扩展分层法和三维有限元法，对带损伤的加筋复合材料板进行了动态热力学分析;建立了热力学扩展层/固元法(TELW/SE)。在TELW/SE中，分别采用热机械扩展层法(TELW)和热机械三维实体单元对板和加强筋进行模拟。利用界面条件组合最终控制方程，保证了位移和温度的相容性，以及内力平衡。该方法可以准确描述加筋复合材料板的分层、横向裂纹和加筋板界面脱粘等几种典型损伤。关键词:分层动力学热力学分析扩展分层法界面脱粘加筋复合材料板横向裂纹披露声明作者未报告潜在的利益冲突。基金资助:国家自然科学基金(12072364,U1933102)和中央高校基本科研业务费专项资金(3122019074)。
