摘要
用 Rayleigh- Ritz法求解了绑结层合板和编织层合板等 3D复合材料层合板中有纤维搭桥的正方形表面脱层的屈曲问题。搭桥纤维被视为连续分布于脱层表面 ,相当于可提供与脱层屈曲挠度成正比的恢复力的线性分布弹簧。算例表明 ,纤维搭桥对提高临界屈曲载荷的作用十分明显。随着纤维搭桥弹性系数的增大 ,临界屈曲载荷能相应提高。
By using Rayleigh Ritz method,the problem is discussed of the delamination buckling of a fiber bridge square surface made of stitched laminates and woven laminates with 3D composites materials.Bridge fiber is regarded as continuously distributing on the surface of delamination,which offers a linear spring of restoring traction that is in direct proportion to delamination buckling deflaction The examples show that the fiber bridge may significantly increase the critical buckling loads And as the elastic coefficient of the fiber bridge increases,the critical buckling loads may also increase
