Friction Coefficient Evaluation on Aluminum Alloy Sheet Metal Using Digital Image Correlation

Technical Paper
2018-01-1223

The coefficient of friction between surfaces is an important criterion for predicting metal behavior during sheet metal stamping processes. This research introduces an innovative technique to find the coefficient of friction on a lubricated aluminum sheet metal surface by simulating the industrial manufacturing stamping process while using 3D digital image correlation (3D-DIC) to track the deformation.
