The result shows that material nonlinear will obviously lower the structural rigidity of [ 45 / 45 ] crossed angle ply shell , but the affect to the structural rigidity of perpendicularity symmetry ply shell is not so apparent 得出材料非线性会使| 45 - 45 |交角层壳的结构刚度显著降低,但对正交对称层壳的结构刚度影响并不明显。
By selecting polynomial displacement function , buckling analyses for isotropic , orthotropic and angle plying laminated plates with built - in symmetric delamination are made . finally , transfer function method is adopted to three - dimensional stress analysis of laminated piezoelectric cylindrical shell . the sensing and actuating effects of three - layered piezoelectric cylindrical shell are presented 采用传递函数方法对正交各向异性有限长简支压电层合圆柱厚壳进行了三维应力分析,并对三层压电圆柱壳的传感效应和作动效应进行了分析。
