摘要
研究了含任意位置脱层的梁 板的后屈曲问题 .采用小参数摄动法 ,导出了系统的一阶和二阶控制方程 ,边界条件 ,连续条件 ,平衡条件及相容条件 .在算例中给出了梁 板的后屈曲响应曲线 ,且与有关文献进行了比较 .
Problem of post buckling of beam plates with a single arbitrary delamination is studied under axial load. Taking a proper asymptotic sequence and perturbation technique, the control equations, the continuity, equilibrium and compatibility conditions of the first order and second order are derived. In the calculating examples, the response curves of post bcukling for the beam plates are presented and compared with available data.
