| 摘 要： | 通过引入剪切变形效应，提出解决多层叠合板在压模中弯曲成指定柱面形状时的模压分布，以及粘合固化后卸模时回弹计算这样一个包括力学正问题与反问题的有效分析方法，并得到了典型封闭形式解答，同时给出计算与实验结果，二者差异在工程精度的允许范围内。

| Abstract: | An effective method of analysis was suggested to solve the both direct and inverse problems of mechanics about mould pressure distribution in cylindrical bending shaping and resilience computation after curing and unmoulding by means of plate theory with consideration of transversal shear deformation.A closed form solution of typical problems was obtained.The discrepancies between computational and experimental results are acceptable in engineering. |
