The ability to withstand dynamic forces that a device will be subjected to during its intended use is critical for any part. The Fort Wayne Metals Materials Testing Laboratory offers several mechanical tests to mimic these forces in order to engineer prototypes, inspect the quality of the product, assess the unknown, and mimic fracture modes for failure investigations.
Tension Testing offered by Fort Wayne Metals Materials Testing Laboratory spans break loads up to 50,000N per ASTM E8. We can accommodate variations in gauge length, sample fixtures, cross-head speed, and temperature ranges from -100°C to 350°C. We also can perform cyclic tests per ASTM F2516 to report the tension properties of superelastic Nitinol.
Fatigue Testing is critical in understanding the materials we work with and recommend for device applications. We offer Rotating Bending Fatigue tests in accordance to ASTM E2948 at constant amplitude and periodic load (strain.) We can also asses a material at multiple stress (strain) levels to develop a full protocol Stress-Life (or Strain-Life) curve and determine the endurance limit. We have the capability to perform the fatigue tests under custom conditions including specified temperatures and submerged in solutions such as deionized water or saline.
We also have a high-stress, low-cycle bend test apparatus. This test method was developed to support applications requiring high strength and high ductility; for example in the suture needle market. Testing can be performed in accordance to ASTM F1874 to determine the force necessary to bend the part. Custom low-cycle ductility testing is also available to meet your specific needs.
Torsion Testing is a useful tool to understand the properties of a length of wire, cable assembly, or HHS® tube. We can assess the performance and response when a sample is subjected to a torque force to execute the designed objective. Related industry standards are ASTM A938, ASTM E143, ISO 7800.
