摘要
基于Von Karman板理论,考虑横向剪切变形,建立了具脱层的轴对称层合圆板的后屈曲控制方程。应用正交配点法,将后屈曲控制方程、边界条件、以及连续条件转化为非线性方程组,然后进行迭代求解。讨论了不同脱层深度和脱层半径对层合圆板的屈曲及后屈曲特性影响,且与有关文献的结果进行了比较。
Based on the Von Karrnan plate theory, the postbuckling governing equations for the axisymmetric laminated cicular plates with delamination are derived. The effect of transverse shear deformation is considered. By using the orthogonal collocation method, the governing equations, boundary conditions and continuity conditions are transformed into a set of nonlinear equations, and the equations are solved with an iterative method. The effects of delamination depth and radius on buckling and post-buckling of the laminated circular plates are discussed. Numerical results are compared with available data.
