中文摘要 | 本文是利用混式應力有限元素法並配合二次脫層準則,探討均勻壓應力負荷作用 於七種不同疊層角度組合和副積層板等排列方式之複合材料積層板,對於層間應力沿橫軸方 向分佈與臨界脫層應力之影響。經由本文的研究,對於積層板疊層排列方式的影響將有更清 楚之瞭解,並可作為相關設計上之參考及提供積層板相關問題的研究。 |
英文摘要 | The interlaminar stresses and free-edge delamination in laminated composite plates under uniform compression were investigated by using the hybrid stress finite element method and the quadratic stress criterion. In the present investigation, the effects of ply orientations, sublaminate arrangements on the interlaminar stress distributions and free-edge delamination were also conducted. With the information of interlaminar stress distributions and critical stress at the onset of delamination of the laminated composite plate, the structural members can be constructed to meet the specific design requirements. |
