Abstract
The NIST Metallurgy Division has initiated a research project to study the friction behavior of automotive alloys during sheet metal forming. The principal driving force behind this research is the variability observed in the friction behavior between the work piece and the forming die during forming that affects the reliability of the numeric models used to predict the friction behavior during sheet metal forming. This creates a significant obstacle impeding the widespread use of the alloys developed to increase automobile fuel economy. While the overall accuracy of the numeric predictions of friction have been improved, many of the models still heavily rely on empirical friction measurements and data. This one-day workshop established a working group composed of experts from the automotive, academic, and materials modeling and measurement communities, to clearly identify the industrial measurement and modeling needs so that appropriate approaches for a solution may be developed. The major conclusions were: a) classical friction models are not adequate in sheet metal forming, b) new measurements that focus on the interaction between surfaces must be developed, and c) new surface characterization measurements and tools that relate surface morphology to the functional behavior must be developed.
