中文摘要 | 本文主要是利用混式應力有限元素法並配合破壞準則分析複合材料積層板承受撓 曲負荷之第一疊層破壞負荷。混式應力有限元素模式採用修正之最小補能原理並考慮層間剪 變形之影響。本文所採用之破壞準則為最大應力、Tsai-Hill、Tsai-Wu 和 Hoffman 等準則 。分析之結果並與現存之一些分析資料做比較。疊層順序、積層板厚度和破壞準則對積層板 之第一疊層破壞負荷之影響亦做了探討。 |
英文摘要 | The first ply failure loads of laminated composite plates were investigated by using the hybrid stress finite element method and the tensor polynomial failure criteria. The hybrid stress model was based on the modified complementary energy principle and took into account the transverse shear deformation effects. All the six stress components were included in the model. The failure criteria used in the present work were maximum stress, Tsai-Hill, Tsai-Wu, and Hoffman. The first ply failure loads of laminated composite plates subject to transverse loading were analyzed and compared with existing solutions. Good agreement was noticed between these solutions. The effects of ply orientations and failure criteria on the first ply failure loads were also conducted. |
