Ding Testing Inspection: Experts in CTOD Testing, Ensuring the Fracture Resistance of Structural Materials
CTOD Testing is a method of evaluating the fracture resistance of materials by measuring the crack tip opening displacement. Ding Testing Inspection's CTOD testing is a key technology for assessing the fracture resistance of materials and welds, predicting the fracture toughness of materials by accurately measuring the crack tip opening displacement.
Service Introduction
Crack Tip Opening Displacement (CTOD) testing technology can accurately assess the fracture resistance of thick steel plates and their welds, and has become a key technology in the design and construction of offshore equipment and large steel structures. In the certification of steel plate weldability, ship classification societies in developed countries around the world require CTOD testing as a main basis for issuing certificates.
CTOD crack tip opening displacement testing is an effective method for evaluating the fracture resistance of materials and welds. By calculating the opening displacement near the crack tip and using the displacement extrapolation interpolation method, the results of the stress intensity factor at the crack tip can be obtained. Industrialized developed countries have widely applied CTOD testing in the manufacturing industry as an assessment method for welds, especially for welds with plate thickness exceeding 50 millimeters, CTOD testing is required according to specifications to evaluate the quality of weld resistance to cracking.
Industry Pain Points
- Lack of effective methods for assessing the fracture resistance of thick plate welds
- Difficulty in predicting the risk of weld cracking
- Difficulty in ensuring the safety of offshore equipment and large steel structures
Service Scope
Ding Testing Inspection's service scope is extensive, covering CTOD testing, including but not limited to:
- Materials: Steel plates, welding materials, etc.
- Welds: Thick plate welds
