摘要
研究了复合材料夹层梁整体弯曲与屈曲问题,利用复合材料夹层梁的轴向位移、弯曲挠度的微分关系,得到了夹层梁的弯曲微分方程,利用此弯曲微分方程可以求得复合材料夹层梁整体弯曲与屈曲的解析解。有关试验证明,夹层梁整体弯曲时该挠度解析解计算精度较高。
In this paper,the integral bending and buckling of composite sandwich beam is researched.Based on the differential relations of the axial displacement and the bending deflection of the composite sandwich beam,the bending differential equation of sandwich beam is obtained.Using the bending differential equation,the analytical solution of integral bending and buckling of composite sandwich beam can be obtained.The experimental results show that the deflection analytical solution of the sandwich beam with integral bending has higher precision.
