| 摘 要： | 考虑材料组份沿板厚度方向按幂律变化的情形,研究了温度均匀变化时固支功能梯度材料(FGM)矩形中厚板的受压屈曲、热致屈曲和考虑热/机械预应力时的屈曲问题,给出了基于Reddy高阶剪切理论研究板屈曲荷载和屈曲临界温度的半解析数值方法.并以Si3N4/SUS304板为例考虑了材料组份、预加应力、横向剪切变形及面内位移约束条件等对FGM板屈曲承载能力的影响.

| Abstract: | Based on Reddy's higher order shear deformation theory, this paper studies the elastic buckling of shear deformable FGM rectangular plates by using a semi analytical approach. The subset problems include compressive buckling, termal buckling, and buckling of mechanically or thermally prestressed FGM plates. Numerical results are presesnted for Si 3N 4/SUS304 plates. The effects of material composition, initial membrane stresses, and transverse shear deformation on the buckling of FGM plates are discnssed. |
