Accurate strain measurement The weight of a clip-on extensometer f25166 cause bending of the wire, and the knife-edges may t2516, damage the wire, or lead to premature failure Secure gripping for varying specimen diameters Accurate turnaround points Instron Solution: Concrete, Asphalt and Rock.

Nitinol Testing requires a thin strip of the material to be pulled in tension at a specified rate. The challenges of testing Nitinol wire to this standard are: The F procedure involves tensioning the sample initially and then bringing it back down. Nitinol is a shape memory, super-elastic alloy that is used extensively in the biomedical industry. It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more.

A specially designed horn with a smooth finish and a contoured surface with a graduated cam allows for easy loading and a stress reduced clamping area on the specimen. These include the lower plateau strength, upper pleateau strength, and the residual elongation.

Email addresses must contain f251 symbol. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.

The second generation Advanced Video Extensometer AVE 2 utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available. Glossary of Materials Testing Terms. Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience.

This allows hands-free grip operation enabling the specimen to be held with both hands, for easy loading.

Pneumatic cord and yarn grips provide a convenient method for clamping fiber, cord, yarns and fine wires to reduce the problem associated with testing these materials.

ASTM F – 18 Standard Test Method for Tension Testing of Nickel-Titanium Superelastic Materials

Mechanical action wedge grips are the most common fixturehowever other types of grips may be used as well. ASTM F covers the tension testing of Nitinol which is a material used to make stents in the biomedical industry.

The AutoX is a high-resolution, long-travel automatic contacting extensometer. 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 g2516 due to specimen creep.


In the video we demonstrate a special type of tension fixture that is most commonly used for testing wire. Onsite Training At Your Facility.
