Closing forces and internal pressure lead to stresses and strains in hydroforming dies.The deflection of the die influences the accuracy of the hydroformed products.The influence of the die geometry on stresses and strains in the die and on the dimensional accuracy of the hydroformed part is being examined fundamentally.Additionally the location of the closing force transmission is discovered to be crucial.Analytical,numerical and experimental investigations have been accomplished.The objectives of this research were to determine the demands on the hydroforming die and to reduce failure-critical stresses.A die concept which inherits the qualities which are found to be essential is presented.
