Biaxial tensile testing

In materials science and solid mechanics, biaxial tensile testing is a versatile technique to address the mechanical characterization of planar materials. It is a generalized form of tensile testing in which the material sample is simultaneously stressed along two perpendicular axes. Typical materials tested in biaxial configuration include metal sheets,[1] silicone elastomers,[2] composites,[3] thin films,[4] textiles[5] and biological soft tissues.[6]
