Mechanical equipment: Biaxial tensile machine

Biaxial tensile machine

Description:
The biaxial tester is a tensile machine equipped with four independently controlled axes, developed for the study of deformation of textiles, films and thin sheets. The clamping system consists of freely moveable clamping rigs mounted on each axis. The axes movements are fully computer controlled; output consists of the force-displacement curves in the two principal directions. The apparatus can be used to investigate the constitutive behaviour, anisotropy and limits of deformation of the material. The types of tests that can be performed are:

Mono-axial stress tests with clamping in one single direction.
Biaxial tests with principal strain ratio's varying between zero and infinity.
Shear tests using a tensile bar clamped over the centreline of the material.
