The biaxial tensile test is used to determine the deformation characteristics of materials. This test is used primarily for research and development as it allows defined stress values in the intersection area of the specimen to be set up and
investigated. These testing machines are produced to customers’ requirements.
Strain measurement is performed using non-contact extensometry in most cases and Zwick provides several solutions for this; measurement of strain distribution is available via collaboration with Zwick’s specialist partners.
