复合材料层合板稳态和瞬态温度分布

Steady-state and transient temperature distributions of composite laminates

用有限元法分析了各种温度边界条件下复合材料层合板稳态和瞬态温度分布。假 定组成层合板的各铺层均为横观各向同性体，但铺设方向可以是任意的。对八节点等 参元提出了一种新的热容阵集中形式，有效地提高了瞬态温度场的计算精度。以算例 讨论了铺设角和铺设顺序对稳态和瞬态温度分布的影响，并着重论述了层合板热传导 规律。

The steady-state and transient temperature distributions of composite lami- nates under various types of heat conductive boundary conditions are investi- gated by using the quasi-3D finite element method. Each ply is assumed to be transverse1y isotropic. The heat capacity matrix 1umping technique is succes- sfully employed to improve the accuracy of the transient temperature fie1d analysis. The effects of the p1y orientation and the stacking sequence on temperature fields are discussed.
