stress variation in cup forming

This book presents stress variation in cup forming of cold and hot rolled aluminum 1xxx alloys through experimental and theoretical comparative analyses. The engineering model developed successfully accounted for very small strain in the elastic domain, which is a limitation of the Voce model. This model is not a physically based material model, but one that depends on the forming tool geometry and measurable tensile parameters.The stress and strain results obtained experimentally as well as those from empirical model developed are presented. The strain results from both analyses were compared using the Voce empirical model. The resultant stress results agreed perfectly.
