摘要
根据 Hellinger- Reissner原理建立了复合材料层板杂交元 ,用于层板热弯曲分析。通过选取应力参数 ,满足了层间剪应力连续和层板表面条件。通过算例验证了本文单元收敛性好。
According to Hellinger- Reissner principle,the paper sets hybrid- stress finite elements for ther- moelastic analysisof composite laminated plates. The stress parameters are chosen to ensure the continuity of stresses across interfaces and conditions on the surfaces of plates.The element is verified to have excel- lent property and extensive application.
