Materials Characterisation Facilities

Sheet formability testing facility

The Erichsen sheet metal tester fitted with an AutoGrid Vario strain measurement system allows the investigation of the material behaviour and forming limits of sheet metals in sheet forming processes such as deep drawing and stretch forming. Majorly used for the investigation of the forming limits of AHSS and UHSS and of newly developed sheet metal alloys.

Specifications

  • 200 kN max blankholder force, 400kN max punch force.
  • Standard test methods: Swift Cup Test ø50mm (heated and unheated), Square Cup test, Erichsen Cupping Test No.5, 27, 40, FLC - Test ø50 (heated and Unheated), 60, 100mm).
  • Special Test Methods: Channel Drawing test (heated and unheated).

Mechanical testing facilities

The Mechanical testing facilities include two 30kN and one 100kN Instron tensile testers, all fitted with optical extensometers. Majorly used by the group to develop material input data for Finite Element Analysis (FEA).

Specifications

  • Standard test methods: Tensile and Compression tests (Heated and Unheated).
  • Special test methods: Three and Four Point bend test, V-bend test, Pure bending test.

Pure bend test - 1st generation

Specifically designed at Deakin University for the characterisation of roll forming materials and to determine material parameters that are important in the roll forming process design. In combination with inverse analysis allows the generation of tensile material input for FEA. Further applications include the analysis of the Bauschinger effect and the development of kinematic hardening models.

Specifications

  • Re-enforced bending arms to allow the testing of steel strip up to a thickness of 6 mm and a maximum yield strength of 1200 MPa.
  • Special curvature gauge for the measurement of the bend radius.
  • Bending - reverse bending possible.

Bench tester

The simple and compact design of the bench tester as well as the simple test sample shape (rectangular strips) enables the use in an industrial environment on a day by day basis and the very rapid collection of material parameters relevant to the roll forming process. Majorly used in industrial studies for trouble shooting purposes and material analysis.

Specifications

  • Limited to a material thickness of 0.4-2 mm.
  • Currently operated manually.
  • Automated data storage and test data evaluation.
