Experimental and Numerical Simulation of Sidewall Curl in Stamped Automotive Parts made from Advanced High Strength Steel


The objective of this research project is to carry out experimental and numerical simulations of the deep drawing process with a view to (1) better predicting the amount of springback in automotive parts made from advanced high strength steel, and (2) to modify the forming process so as to better control and reduce the springback. To this end, U-shaped channel sections will be formed in a research die, and numerical simulations of these experiments will be performed with state-of-the-art material models. A range of process changes will then be virtually implemented to identify process parameters that minimize the amount of springback.  This will enable the partner organization to reduce the time required to design draw dies as well as improve the quality of the parts they manufacture.
