Abstract [eng] The paper contains an investigation of hydroforming technology, by implementation local necking criterion in finite element code. It is known that even for expansion deformations a local necking takes place before failure. Four necking criteria were implemented in FEM code to predict plastic instabilities in hydroforming technology and the results of numerical experiments of failure prediction are presented.
