| 摘 要： | 改进了复合材料层板高阶剪切变形理论。改进后的理论与一阶剪切变形理论同样只有5个独立变量,但考虑了横向剪切应变沿板厚呈二次曲线变化及满足了层间剪应力的连续性。该理论比简单高阶理论计算的位移和应力更为精确,且逼近三维弹性解。

| Abstract: | A high-order shear deformation theory of laminated composite plates is proposed. The improved theory contains the same independent unknowns as in the first-order shear deformation theory, but acounts for parabolic distribution of the transverse shear strains through the thickness of the plate and the continuity of transverse shear stresses between layers. The present theory predicts the deflections and stresses more accurately when compared with the Reddy's theory. |
