AbstractThis scientific paper is concerned with development of hybrid and combined technologies of sheet pressing which use static and dynamic loadings. Unique in world practice technological schemes of a number of operations have been developed, patents of the RF for these schemes have been taken already or are executing. A possibility of use of the multi-purpose finite-element complex ANSYS/LS-DYNA for computer simulation of coupled static-and-dynamic processes has been demonstrated with concrete examples. The technique of computer simulation of coupled problems has been developed; the complex of experimental investigations of processes “stretching – forming” and “bending – flanging”, confirming the advantages of combined operations, has been performed. Within the extent of experimental-and-industrial checking the machining attachment for a number of new technologies developed has been designed and produced, sampling of them has been carried out. Photos of the finished parts produced with these technologies are given. Technical-and-economical advantages of the technologies developed have been formulated.
