本案例復現了Engineering Structures上的某篇論文（Finite element modelling of debonding failures in steel beams flexurally strengthened with CFRP laminates）CFRP加固鋼梁脫粘破壞的有限元模擬。

Extended Finite Element Method(XFEM)引進非連續位移函數以及裂紋尖端增強函數到位移場中，處理傳統有限元法設置麻煩的問題，還可以模擬裂紋成長。在2016年以前的版本XFEM是使用domain integral來計算J積分的值，其結果較不穩定，2017年后引進了line integral的方式后計算精確度也大幅提升。

借用自己上有限元應用這門課第一節課的結束語來說就是： Finite Element Analysis is a very powerful tool. However, always question the results and check for plausibility. 對于結果的分析包括了結合工程經驗以及土力學、有限元理論的分析。
