| 中文摘要: |
| 提出一种新的精化高阶理论，该理论满足层间位移、应力连续条件，由此建立了三角形精化板单元。该单元满足单元间Ｃ１类弱连续条件，其收敛性得到保证，且具有简单、高效率的优点。 |
| 英文摘要: |
| A new higher order shear deformation theory of composited laminates, which fully satisfied the geomatric and stress continuity conditions at interfaces, and refined triangular element are proposed. The interelement C 1 weak continuity conditions can be satisfied, so that the convergence are insured. Numerical results are shown that the present element has higher computational efficiency and higher accuracy. |
