Uticaj nemonotonosti deformisanja i promenljivih triboloških uslova na obodu tokom procesa dubokog izvlačenja

Abstract

Influence of two types of variable blank holding force (decreasing and increasing character) in two-phase nonmonotonous thin sheet forming process is considered in this paper. First phase is biaxial tension (stretching) and second pure deep drawing. Following properties are monitored: main surface strain distributions, thinning distributions, deformation force change and drawing depth change.Results clearly shows significance of variable blank holding force influence on deep drawing process.
