在本篇研究中，本文將透過一個非線性之破壞分析模式，針對複材疊層板承受單軸壓力作用下，進行材料之破壞預測及分析探討。此非線性破壞分析模式，主要包含了三大部分，即材料破壞前的非線性組成律、預測破壞時機之混合破壞準則及後破壞分析模式。
在複材單層板破壞前之非線性行為模擬，是假設材料之軸向及側向均為彈塑性行為，而剪力行為則使用了非定值之剪力參數來描述材料之非線性行為。至於破壞時機之研判，則使用了結合Tsai-Wu破壞準則及最大應力破壞準則之混合破壞準則來作預測。在後破壞行為中，對單層板軸向應力及剪力行為採用了脆性破壞模式，而對單層板側向應力則採用了逐降模式來作模擬。
最後，對於所提出之非線性破壞分析模式之預測結果，將分別與實驗值及其他分析模式之預測結果相互比較，以證明在單軸壓力作用下，本文所建議之分析模式較合理且精確。
