This PhD project is part of the Cotutelle arrangement between Coventry University, UK and Deakin University, Melbourne, Australia. The successful applicant will spend 2 years at Deakin and 1.5 years at Coventry, with a supervision team drawn from the two Universities.

The Project

Roll forming, where a flat sheet is incrementally bent into shape in successive roll stands is increasingly used for the forming of high strength steels for high end products in transportation industry. With increasing material strength, the effect of material property variations on the final component shape becomes more significant. To achieve high component quality and process robustness new methods for in-line material property monitoring and part shape control need to be established.

Deakin University has developed a simple bending test that can be used on the shop floor for the monitoring of material properties from coil to coil. Combined with numerical analysis and a simple inverse routine the bend test allows identifying residual stress profiles in the incoming strip; this information can be used in FEA to achieve an improved representation of material behaviour in the process. Deakin also developed a new approach for in-line shape control. Here roll load and torque measurements in combination with FEA analysis are used to identify property variations in the incoming material. It is likely changes in material strength and residual stress influence the final shape and therefore need to be considered for final part shape adjustment.
