裂缝力学检测服务

Manufactured materials are not immune to experiencing cracks, flaws, or defects. Our materials testing experts measure the fracture mechanics of both nonferrous and high-strength ferrous materials to provide manufacturers with valuable insight into the allowable stress levels and overall durability of their product.

CTOD测试

Crack Tip Opening Displacement, or CTOD, is a measure of the crack length or physical opening of the fatigue crack tip at the point of failure. CTOD testing measures the toughness of materials that tear before failure and provides a single value at the first sign of instability. CTOD testing typically results in one of three types of failure:

CTOD测试通常导致三种类型的故障之一：

样品在弹性区域中以脆性方式失效，或者在变形开始后不久。
The sample fails in a brittle manner after stable tearing has started and the load is still increasing at the time of fracture.
在样品不能再容纳施加的负荷和不稳定的撕裂时，近乎发生故障。

Testing K1C Value

The KIC test (sometimes referred to as KIC, or K1C) is used to determine the brittle fracture toughness of metallic materials. Most often associated with ASTM E399, the Linear-Elastic Plane Strain Fracture Toughness test, or KIc value, is performed across a range of temperatures to determine the design, life calculations, and crack growth, or remaining life calculations. A valid KIC test ensures that the test specimen fractures under nominally linear elastic conditions.

Testing J1C and JR Values

基于J的测试测量裂缝延伸期间释放的能量。该标准化测试方法用于评估具有高韧性和低强度测量的材料。乐动娱乐官网就像CTOD测试一样，JIC或JR测试测量失败前材料的不稳定性，但更为关注延性撕裂。

T-Notch测试

Choosing the appropriate test method and standard is dependent on the behavior of the material being evaluated. Metallic materials, like aluminum, present linear-elastic behavior. Whereas plastics, polymers, and other non-metallic materials exhibit elastic-plastic behavior.
