Bend Test Facilities

Pure bend test – 1st and 2nd generation

This test was 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, this produces tensile material input for FEA. Further applications include the analysis of the Bauschinger effect and the development of kinematic hardening models.

Specifications

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

 

 

Bench tester

The simple, compact design of the bench tester, as well as the simple test sample shape (rectangular strips), enables its use in an industrial environment on a day-by-day basis. It also affords the very rapid collection of material parameters relevant to the roll forming process. It’s used heavily in industrial studies for troubleshooting and material analysis.
