Fracture toughness test

Where to do fracture toughness testing? BAIJIAN material testing agency can provide fracture toughness testing services, third-party materials laboratory, high-tech enterprise, CMA qualification certification agency, complete laboratory instruments, strong scientific research team, can provide you with industrial Provides services such as problem diagnosis, identification of unknown substance components, foreign matter analysis, material identification, brand identification, performance testing, composition analysis and other services. It usually takes 7-15 working days to issue a test report. The test report supports the QR code system to check the authenticity. Many companies across the country The laboratory branch supports nationwide door-to-door sampling/sample delivery testing services.

Test period: 7-15 working days

Testing fee: Initial inspection of samples. After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment.

Fracture toughness test range

Metal materials, epoxy composite materials, plastics, titanium alloys, carbide, films, glass, nylon aviation materials, refractory materials, ceramic materials, high strength Aluminum alloy, tough and brittle steel, calcium carbonate reinforced polypropylene composite, rock, high-strength steel, carbide, wood, thin-walled structure, alumina, pipeline steel, etc.

Fracture toughness test items

Fracture toughness test, indentation fracture toughness test, fracture toughness test, tensile fracture toughness test, welding fracture toughness test, stress intensity factor test, material surface Fracture toughness test, dynamic fracture toughness test, fracture toughness KIC value test, fracture toughness and yield strength test, fracture toughness and tensile strength test, dynamic fracture toughness test, damage strength and fracture toughness test, etc. (At most testing needs, you can communicate with our online laboratory to answer your questions about the experimental process and cycle.)

What are the uses of BAIJIAN third-party test reports? What problems can it help you solve?

1. Analyze the reasons for use. (If you encounter some difficult problems, you can solve them through test report data)

2. Improve product quality. (By comparing test data, we can discover the problems of our own products, improve product quality, and reduce production costs)

3. Use of scientific research paper data.

4. Diagnosis of industrial problems.

Fracture toughness test related information

Fracture toughness is the occurrence of cracks or crack-like defects in the specimen or component. The starting point no longer breaks rapidly as the load increases, that is, the resistance value displayed by the material when so-called unstable fracture occurs. Such a fracture toughness value can be expressed by a single parameter describing the mechanical state of the crack tip, such as energy release rate g, stress intensity factor K, crack tip opening displacement CTOD and J integral.

BAIJIAN sample sending and testing process
