| 摘 要： | 复合材料及其结构的热响应是近年来复合材料力学研究的热点课题之一。本文用有限元法研究了复合材料加筋板的热变形和热应力。基于Mindlin假定导出了一阶剪切变形层合板梁理论。这两种理论也适用于中厚板和深梁。考虑的热载可以是瞬态的也可以是稳志的,实际工程应用表明,根据本丈模型研制的计算机程序具有较高的计算精度和效率。

| Abstract: | Response of laminated composite structures to thermal surround ings has been a subject of intensive studies in recent years. The thermal behaviors of laminated composite plates and shells have studied well. In this paper, the thermal deformations and stresses in stiffened composite laminates are investigated by using finite element method.Based on Mindlin hypothesis, laminated composite plate and beam theories including the effect oftransverse shear deformationane given. The fosegoingtheories are also applicable to thick plates and beams. The thermal loadings considere dare transient as well as steady. The corresponding computer code are developed. The application of the present model and code to practical problemshas shown that they are accurate and effective. |
