断裂韧性测试

Element delivers a wide range of fracture toughness and mechanics testing services to help you estimate the life of your components, 减少维修费用, 改善设计, 延长组件的预期寿命.

断裂韧性试验是一种 力学试验方法 used to determine the energy needed to initiate and cause failure within a material. 它也可以与…结合使用 疲劳测试, 腐蚀测试, and 升高的温度 to determine the useful life of the material under different conditions. 

我们的断裂韧性测试服务

采用先进的技术和设备, our experts provide valuable insight into material performance, 帮助你做出关于安全的关键决定, fitness, 金属的寿命, non-metallic, 先进材料. 作为机械测试的单一来源供应商, we can assist in creating a testing program that gives you confidence in your products and materials. 

Our services include characterizing fracture toughness through single point critical values (CTOD, J integral, and K) as well as tearing resistance diagrams (J-R and CTOD-R curves), 遵循BS 8571等国际标准, ISO 12135, ASTM E1820, ASTM E1921.

断裂韧性试样几何形状 

Element is well equipped to perform this testing and analysis on a vast range of specimen size and crack geometries, 包括但不限于: 

• 紧致张力(CT)
• 中张力(MT)
• 单刃缺口张力(SENT)
• 单刃缺口弯管(SENB或三点弯管)
• 扩展紧致张力(ECT)
• 中心开裂张力(CCT)
• 表面裂纹张力(SCT)
• 模式I, II和III加载下的复合材料

材料等级和断裂力学测试能力 

我们的专家测试高强度铁, nonferrous, polymer, and composite materials using advanced computer-controlled servo-hydraulic test frames. Coupled with decades of experience and many successful applications, 先进的设备控制, processes, and data acquisition methods allow us to guide you on even the most complex test results. 

There is also the possibility to create a custom testing analysis and accommodate any request for non-standard fracture mechanics testing protocol for your specific application or environment. im体育APP提供了 Fracture Mechanics and Toughness Testing in Sour Environment (in-situ) for the oil and gas industry as their pipelines and equipment are often exposed to sour service gases and liquids. 我们为能源im体育平台app下载提供的服务还包括 根据ASME B31进行氢气管道系统测试.12.
