Trimming of AA6111-T4 and AA5754-O Automotive Aluminum Sheet Materials
Trimming behaviour of automobile aluminum alloy sheet materials AA6111-T4 and AA5754-O were studied using experimental and FE simulation approaches. Three tool configurations with different selections of tool parts were utilized to study the effects of clearance and punch speed. Results were analyzed in terms of punch force and displacement traces and cut edge morphologies. Finite element code ABAQUS/Explicit program was used to simulate the trimming process with 2D plane strain models. A fracture strain was experimentally measured and utilized in FE modeling for fracture initiation and development using the element deletion technique. Results from FE simulation for both materials were compared with experiments and good agreement was obtained for most of the studied trimming conditions.
