AB Nowadays, when there is strong tendency to still accelerate production process and thus save time and money, is very necessary to take into account influences of the individual process parameters on forming process. Another tendency tries to reduce weight of parts at keeping the required mechanical properties. These aspects lead also to utilization numerical simulations for modelling processes and materials with the specific utility properties. This paper deals with the influence of load-rate (thus also strain-rate) on the own process of metal sheet forming (namely U-die bending) - in light of both achieved deformation and subsequent spring-back of material. Field of titanium and its alloys application for the engineering industry is closely related especially with its suitable ration between strength and density. Deformation and subsequent spring-back was investigated by the numerical simulation in the software PAM-STAMP 2G.
