Fracture & Fatigue Crack Growth Test Equipment
|
TestResources has considerable expertise at delivering turnkey solutions to the needs of fracture mechanics researchers and test labs. We offer both static and dynamic test machines equipped with fixturing, environments and test software for metals and other materials applications. Fracture toughness tests describe the ability of a material having a crack to resist fracture. They have historically been important to welded joints and considered an input parameter for fracture-mechanics based assessments for fitness-for-service. Most standards (ASTM E399, ASTM E1290 and ASTM E1820) were written with metals in mind but can be adapted to other materials. Our equipment for fatigue crack growth and propagation tests (ASTM E647) is more specialized, including high precision machine control, potential drop instrumentation, specialized applications software and expertise.

More Info: Test Machine Selection - Helpful Considerations
| Least Expensive Test Machine Considerations |
- It is important to discuss your application requirements with a TestResources applications engineer. Clearly understood requirements lowers risks by eliminating potential misunderstandings that increase costs. Help us understand your goals and needs and you will save money with TestResources.
- Our product line is modular or 'lego-like' which makes it possible buy very affordable configurations and delay expenditures until they become a requirement. Our modular line spans requirements from 'least expensive' to 'most flexible and versatile'.
- A machine that utilizes a standalone controller is much more affordable than one that requires a computer. Standalone controllers feature optional software that enables use to expand to a PC, including control of the test machine, export of data to a PC, curve plotting and analysis of data. A standalone controller also is a better choice in many production testing applications.
- Finally, the machines force/speed requirements impact the price of the machine. Higher forces and fast speeds demand bigger motors and increase the purchase price.

| Most Versatile Test Machine Considerations |
- Versatility implies being able to reset the machine for different materials, different test methods, and different operators on an as needed basis.
- A PC based controller is more versatile than a standalone controller. Versatility is valuable where test demands or operators change often and in cases where the test requirements are unknown - such as research and testing service lab environments.
- A dual column load frame has more versatility than a single column frame but cannot then be used easily for testing large samples or mounting a large temperature chamber. The good news is that our product line is modular or 'lego-like' which makes it inerently versatile. It is possible to buy very affordable configurations and delay expenditures until they become a requirement. Our modular line makes it possible to decide where to spend monies to increase versatility or not.
- A high force rated test machine performs more tests than a low force rated machine. Higher forces and faster test speeds require bigger motors and increase the purchase price. The addition of a low force load cell is all that is needed to perform low force measurements.

| Do you need to perform fatigue tests? |
- A fatigue test machine is capable of performing virtually any and all mechanical tests. These include static tensile, compression, peel and tests such as stress relaxation and creep. In addition a fatigue tester can generate dynamic impact tests, simulate loading service conditions, perform high cycle tests that last millions of cycles.
- Multichannel tests, such as biaxial tests, are most commonly configured as fatigue testers for a variety of reasons.
- The term 'cyclic' tester may refer to an electromechanical test machine that can cycle (slowly) between position or load limits. We differentiate that type of machine from our fatigue tester.
- It is critical to discuss your fatigue application requirements with a TestResources applications engineer. Clearly understood requirements lowers risks by eliminating potential misunderstandings that increase costs. Help us understand your goals and needs and you will save money with TestResources.
