CTOD test to evaluate the fracture toughness of structures with defects! Ideal for preventing unstable fracture.
The "CTOD (Crack Tip Opening Displacement) test" is one of the tests used to evaluate the fracture toughness of structures with defects. When a specimen with a crack is held at a specified temperature and subjected to bending forces, a phenomenon called "unstable fracture" occurs, where the crack rapidly propagates. This test measures the crack tip opening displacement (CTOD value) just before the crack begins to propagate rapidly. 【Applicable Targets】 ■ Welded joints of carbon steel ■ Welded joints of low alloy steel ■ Welded joints of high-strength steel ■ Welded joints of low-temperature steel *For more details, please refer to the catalog or feel free to contact us.
