斷裂韌性測試（Fracture Toughness Test）是用于測量材料抵抗裂紋擴展能力的實驗方法。以下是綜合多個來源的詳細解釋：
斷裂韌性的定義
斷裂韌性（Fracture Toughness）是材料在存在裂紋時抵抗斷裂的能力，通常用應力強度因子的臨界值（如$K_{IC}$）或裂紋尖端張開位移（CTOD）等參數表示。它反映了材料在裂紋尖端應力集中條件下的抗裂性能。
測試的核心目的
該測試通過模拟材料在實際工程中的裂紋擴展場景，确定材料的臨界斷裂韌性值。這些數據常用于評估結構的安全性，例如壓力容器、管道或航空航天部件的適用性。
常見測試方法
應用領域
測試結果廣泛應用于材料研發、質量控制及工程失效分析，尤其在核能、石油化工等對安全性要求高的領域。
若需了解具體測試标準或實驗步驟，可參考（TWI）和（海詞詞典）提供的專業術語解析。
破裂韌性試驗用于評估材料的破裂韌性。在試驗中，通過施加壓力或拉力等外力，使材料發生破裂，記錄下破裂前後的變化，從而評估材料的破裂韌性。破裂韌性試驗在材料科學、機械工程、建築工程等領域得到廣泛應用。
