Biaxial Tensile Test

A distinctive feature of materials testing is the biaxial tensile test or two-axis tensile test, used to determine the deformation properties of materials It is primarily employed in research and development, as it allows defined stress values to be set and investigated at the intersection point of the specimen.

Both standardized and customized biaxial testing machines are available from Zwick

  • horizontally oriented biaxial testing machine with electro-mechanical testing actuators for uniaxial or biaxial tests on films/foils, paper, elastomers and biological materials up to a maximum test force of 2 kN
  • vertically oriented biaxial testing machine with electro-mechanical testing actuators for uniaxial or biaxial tests on sheet metals, elastomers, plastics and components up to a maximum test force of 50 kN
  • horizontally oriented biaxial testing machines with table-top testing machines for uniaxial or biaxial tests on sheet metals, elastomers, plastics and components up to a maximum test force of 150 kN
  • vertically oriented biaxial testing machines for uniaxial or biaxial tests on sheet metals up to a maximum test force of 250 kN

Control options for biaxial testing machines

Depending on requirements, three types of control are available:

  • master-slave operation with 'electric shaft'
  • strain control
  • strain control with additional mid-point control

Strain measurement in biaxial tensile tests

Strain measurement and strain control are usually on an optical basis via the proven videoXtens extensometer.
