非均匀圆柱型正交各向异性圆板的弯曲

BENDING PROBLEMS OF NON UNIFORM CYLINDRICAL ORTHOTROPIC CIRCULAR PLATE

  • 摘要: 研究了非均匀圆柱型正交各向异性圆板在均布横向载荷作用下的弯曲问题,求得了折算刚度随半径按指数规律变化的非均匀圆柱型正交各向异性圆板弯曲问题的渐近解,给出了周边固支和简支条件下的渐近解.通过算例可以看出,这种非均匀性对圆板中心挠度的影响是显著的

     

    Abstract: The bending problems of non uniform cylindrical orthotropic circular plate under uniformly distributed transverse load is studied.Asymptotic solutions for the bending of cylindrical orthotropic circular plate with reducing stiffness varying exponentially with radius are obtained. The asymptotic solutions of such circular plates with rigidly fixed edges and simply supported edges are given. The calculation examples show the influence of non uniformity on the maximum deflection.
