本研究針對開孔纖維複材板受集中載重及側向箝制之下，使用一套非線性破壞分析模式，進行材料之破壞預測及破壞行為分析探討。此非線性破壞分析模式主要包含三部分：（1）材料局部破壞前的非線性組成律，（2）材料局部預測破壞時機的混合破壞準則，（3）材料局部破壞後的後破壞分析模式。
模擬複材單層板破壞前之非線性行為，係假設材料在軸向及側向均為彈性－塑性行為，剪力參數則使用非定值來模擬之。判斷材了局部破壞的依據，則使用混合破壞準則。在後破壞行為分析中，單層板軸向和剪力之行為皆假設為脆性破壞模式，側向採用逐降破壞模式模擬之。
最後，非線性破壞模擬並且分析結果，將與開孔複材板受插銷集中載重及側向箝制作用之實驗數據加以比較，驗證明本論文所建議之分析模式是否適用。

In this study, using a nonlinear failure analysis model, for predicting the response of composite laminate, which has pin concentrated load on the hole and lateral constrained load with washers. A nonlinear failure load analysis mode, which includes nonlinear constitutive law, mixed failure criterion and post failure mode.
The fiber and matrix are assumed to have elastic-plastic behavior and to behave nonlinear with a variable shear parameter, as the composite lamina being in the pre-damage region, which the response of an individual lamina within the laminate is described by the nonlinear law. Beginning the local damage on individual lamina is detected by the mixed failure criterion, which is composed of Tasi-Wu failure criterion and maximum stress criterion. The fiber and in-plane shear are assumed to exhibit brittle behavior, and the matrix is assumed to exhibit degrading behavior.
Finally, the nonlinear failure analysis model has been compared with the experimental results and the predictions by other criteria. It is proved that the model is suitable analysis model to predict the response of composite laminate, which has pin concentrated load on the hole and lateral constrained load with washers.
