Testing Machines for Biaxial Tensile Tests 

A unique feature of materials testing is the biaxial tensile test or biaxial tensile test. which is used to determine the deformation properties of the material. 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.

Key Advantages and Features

Description

Biaxial testing machines are available from ZwickRoell in both standardized and customized versions.

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

Strain measurement

Strain measurement in biaxial tensile tests

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

Types of control

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
