INVESTIGATION OF CALOTTAN SHEET STIFFENING PROCESS

Abstract

This investigation revealed that metallic sheet materials when cold formed in the CALOTTAN stiffening pattern show increased rigidity and impact resistance worth considering in equipment design. However, this pattern like all stiffening patterns known to the authors displays preferred axes of rigidity. The investigation also showed that rigidized metallic sheet available in the United States from X Company is approximately as efficient as calottized sheet.
