Glossary of Materials Testing Terms. Accurate strain measurement The weight of a clip-on extensometer may cause bending of the wire, and the knife-edges may slip, damage the wire, or lead to premature failure Secure gripping for varying specimen diameters Accurate turnaround points Instron Solution: This article will provide a brief overview of the test as well as recommend the perfect grip for a successful tensile test.

ASTM F Tensile Testing of Nitinol Wire – Instron
Nitinol Testing requires a thin strip of the material to be pulled in tension at a specified rate. For thicker diameter wire, we recommend using 5kN pneumatic side action grips with serrated faces. Email addresses must contain the symbol. The second generation Advanced Video Extensometer AVE 2 utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available.
Description Literature Aatm Us Nitinol is a shape memory, wstm alloy that is used extensively in the biomedical industry.
Nitinol, also known as Nickel-Titanium, is a highly elastic metal that also has shape memory.
ASTM F covers the tension testing of Nitinol which is a material used to make stents in the biomedical industry. Mechanical action wedge grips are the most common fixturehowever other types of grips may be used as well.

These unique properties make it very useful in a host of other applications including kidney stone retrieval baskets, eye glass frames, and micro antennas. Asstm Universal Software is built from asmt ground-up for touch interaction and an intuitive user experience.
Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Software for Series Systems. Both the AVE 2 and AutoX are capable of measuring strain in cyclic loading and to failure without damaging the Nitinol wire. Subscribe to Our Newsletters.

The F procedure involves tensioning the asfm initially and then bringing it back down.
ASTM F2516-14 Tensile Testing Nitinol Wire
It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more. These include the lower plateau strength, upper satm strength, and the residual elongation. The clamping mechanism can be activated either automatically or through a foot switch. In the video we demonstrate a special type of tension fixture that is most commonly used for testing wire. Pneumatic cord and yarn grips provide selectable clamping force to accommodate different materials and excellent follow-up action which compensates for decay of the holding force due to specimen creep.
The AutoX is a high-resolution, long-travel automatic contacting extensometer.
