摘要: 本文用减少弯曲刚度法把考虑横向剪切变形影响的非对称层压板的弯曲问题形式上作为对称问题来处理,从而大大简化求解过程.从数值结果看,只要铺层数大于2,使用减少弯曲刚度法所产生的误差很小.Abstract: In the paper, tiLe reduced bendinb stiffnss (RBS) method is used to treat the bending of ussymmetricwlly laminated plates as symmetrical problems in form so that transverse chear deformation is considered.Then their solution procedures are greatly simplified.Numerical results show that the RBS method is found to yield Bufficient accuracy when the number of laminates is greater than 2.
