Based on the third order zigzag displacement model, a bending theory for laminated composite plates in an initially stressed state is derived by use of the principle of virtual work.
基于三阶折线位移模型，利用虚功原理导出了含初始平面应力的层合复合材料板的弯曲理论。

The influence degree of furniture material to breaking bending moment and rigid efficiency in bamboo glue-laminated panel is bigger than those in medium density fiberboard and particleboard orderly.
Aimed at the bend of poplar-straw laminated beam, the theory of delamination shearing deformation was used to analyse its bending deflection and strength, and compared the results with other theories.
