Abstract Details

1997, Master of Science, Ohio State University, Materials Science and Engineering.
The wrinkling and springback characteristics of aluminum and copper systems in electromagnetic sheet metal forming and electromagnetic ring compression have been studied. Several material and process parameters have been varied and their effects on wrinkling and springback have been documented. The sheet metal forming experiments were carried using a pancake coil. The effect of energy of forming (on 1100 - O aluminum), thickness of the sheet metal (on 1100 - O aluminum), temper of the metal (by comparing the O temper with the T6 temper), die geometry, stand-off distance and material (by comparing 1100 - O aluminum with Oxygen Free High Conductivity copper) have been analyzed. The springback measurements were made using a Coordinate Measuring Machine (CMM). Wherever possible, formability data has been presented. A few applications and capabilities of the electromagnetic sheet metal forming process have been demonstrated. The ring compression experiments were carried out using a single turn coil. The effects of energy (on 6061 - O aluminum), ring thickness (on 6061 - O aluminum), ring height (on 6061 - O aluminum), temper of the metal (by comparing 6061 - O with 6061 - T6), the radial compressive strain and material (by comparing 6061 - O with copper) have been analyzed. The clamping force (between the rings and the mandrels onto which they were compressed) has been used as a measure of springback. Possible explanations have been suggested for the observed trends, both in sheet metal forming and in ring compression.
