About Elastic Bands
Elastic bands are commonly used for testing at near room temperature.
The contact force may be varied by the cross-section size of the elastic
band and its overall length. Elastic bands can be used by all axial
extensometers.
•
Elastic bands (rubber bands) of the type provided with the
extensometer are available from stationery supply stores.
•
Orthodontic elastic bands may also be used and are available from
medical supply houses.
Round specimens
An elastic band attachment method can be used with round specimens.
Each knife edge requires a band to secure it to the specimen.
Flat specimens
An extensometer can be mounted to a flat specimen with elastic bands
using a disk or wireform attachment. When using a wireform
attachment, it is necessary to replace the attachment adapters with knife
edge hold-downs.
