摘要
本文提出了一种简单高阶剪切变形层板理论。其位移场满足层间位移和横向剪应力的连续性,τ_(xx)、τ_(yx)在板面等于与板面平行的载荷。位移场的变量与一阶剪切变形理论一样只有五个,但无论厚薄板均逼近精确解。文中合理考虑了层板板面上与板面平行的载荷对层板的作用,大大改善了这类问题解的精度。
A simple higher-order shear deformation theory for laminated composite plates isdeveloped.Its displacement field accounts for the continue of displacement and shear stressesbetween layers,and ensure that τ_(xz)、τ_(yz)on the plate surfaces are equal to the loads.Thetheory contains the same unkows as in the first-order shear deformation theory,but itssolutions are much more exact.The theory includs reasonably the affect of loads parallelingthe plate surfaces,and the precision for analysing these problems is improved considerably.
