Testing Machines for Cruciform Tests 

A unique feature of materials testing is the biaxial tensile test, or two-axis 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, low-load testing machine with four high-resolution linear drives (horizontally oriented) for uniaxial and biaxial testing of natural and artificial elastic tissues up to a maximum test load of 2 kN
  • Biaxial testing machine with electromechanical testing actuators (horizontally oriented) for uniaxial or biaxial tensile tests on films/foils, paper, elastomers and biological materials up to a maximum test load of 2 kN
  • Biaxial testing machine with electromechanical testing actuators (vertically oriented) for uniaxial or biaxial tensile tests on sheet metals, elastomers, plastics and components up to a maximum test load of 50 kN
  • Biaxial testing machines with table-top testing machines (horizontally oriented) for uniaxial or biaxial tensile tests on sheet metals, elastomers, plastics and components up to a maximum test load of 150 kN
  • Biaxial testing machines (vertically oriented) for uniaxial or biaxial tensile tests on sheet metals up to a maximum test load of 250 kN

Strain measurement

Strain Measurement for Cruciform Tests

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

Types of control

Types of control for cruciform testing machines

Depending on the requirements, three types of control are available:

  • Master-slave operation with “electric shaft”
  • Strain control
  • Strain control with additional mid-point control
