Applied Technical Services (ATS) Provides Fatigue Testing
ATS Best Practice Fatigue Testing Methods
ATS engineers are aware that each product, material, or specimen brought into the lab will have a certain level of articulation in service. Depending on the complexity of articulation, as well as other factors, ATS designs customized test programs and fabricates the required fixtures for specific fatigue testing scenarios. Through best practice testing methods, ATS is able to also test for fracture toughness, Crack-Tip Opening Displacement (CTOD), and high-temperature tensile properties.
ATS Machine Capabilities Include:
- Load Capacity: 2 lbs. to 55,000 lbs.
- Temperature Range: Ambient to 1000 degrees Celsius
Fracture toughness tests are typically completed within the design stage. These tests are built to determine the exact amount of stress needed to propagate an existing defect (or flaw) within the specific material.
Crack Tip Opening Displacement (CTOD)
CTOD is a type of fracture toughness test. It is used to measure if a material can be used during particularly strenuous working conditions. Specifically, CTOD testing measures plastic deformation at the crack tip, as it appears during stable tearing. It is important to note that this type of test is often used on materials that have high toughness levels, but don't produce valid KIC with the ASTM E399 standards.
