| 摘 要： | 本文用力法求解了不同材料的受压简支正交异性矩形脱层的屈曲和后屈曲问题,并给出了有关的数值结果.结果表明,无量纲临界屈曲载荷随着矩形脱层长宽比的减小而增大;随着载荷的增大,脱层中点的挠度逐渐增大而成为大变形,且挠度与载荷呈非线性关系.

| Abstract: | The delamination in a laminate will buckle and postbuckle under a sufficiently large in-plane compression.The problems of buckling and postbuckling of simply supported orthotropic rectangular delaminations for different material properties under compression have been solved by means of deflection-force function method in this paper.The corresponding numerical results are provided.The result shows that the nondimensional critical buckling load increases with the decreasing of the aspect ratio of the rectangular delemination,the central deflection of rectangular delemination increases with the increasing load and becomes moderately large. |
