在本篇研究當中，使用一套非線性破壞分析模式，針對開孔纖維加強複合材料疊層板承受雙軸張應力作用下，進行材料之破壞預測及分析探討。此非線性破壞分析模式包含三部分：
　　1. 材料破壞前的非線性組成律
　　2. 預測破壞時機的混合破壞準則
　　3. 後破壞分析模式。
對於開孔複材單層板破壞前之非線性行為，均假設材料在軸向(纖維)及側向(基材)均為彈性-塑性行為，而面內剪力則使用定值剪力參數來描述之。對於用於破壞時機之預測，則結合Tsai-Wu破壞準則及最大應力準則，稱之為混合破壞準則。後破壞分析模式中，對單層板軸向及剪力之行為假設成脆性破壞模式，而側向則採用逐降模式模擬之。

　　該非線性破壞分析模式所預測之結果，將分別與開孔複材疊層板之實驗數據結果做比較，以證明纖維加強開孔複合材料疊層板在雙軸拉力作用下，本文所建議之分析模式正確且合理。最後，將影響複材疊層板強度的三種因素：孔徑、疊序及應力比三者之間相互做一系列的探討，以期能適切應用於工程上。
