断裂韧性测试（Fracture Toughness Test）是用于测量材料抵抗裂纹扩展能力的实验方法。以下是综合多个来源的详细解释：
断裂韧性的定义
断裂韧性（Fracture Toughness）是材料在存在裂纹时抵抗断裂的能力，通常用应力强度因子的临界值（如$K_{IC}$）或裂纹尖端张开位移（CTOD）等参数表示。它反映了材料在裂纹尖端应力集中条件下的抗裂性能。
测试的核心目的
该测试通过模拟材料在实际工程中的裂纹扩展场景，确定材料的临界断裂韧性值。这些数据常用于评估结构的安全性，例如压力容器、管道或航空航天部件的适用性。
常见测试方法
应用领域
测试结果广泛应用于材料研发、质量控制及工程失效分析，尤其在核能、石油化工等对安全性要求高的领域。
若需了解具体测试标准或实验步骤，可参考（TWI）和（海词词典）提供的专业术语解析。
破裂韧性试验用于评估材料的破裂韧性。在试验中，通过施加压力或拉力等外力，使材料发生破裂，记录下破裂前后的变化，从而评估材料的破裂韧性。破裂韧性试验在材料科学、机械工程、建筑工程等领域得到广泛应用。
