Influence of crystallographic texture on plastic instability in sheet metal forming

The problem of plastic instability in sheet metal forming processes is considered. The mathematical model, which determines the limit strains under plane stress state as a function of parameters of crystallographic texture, is suggested. As an example, the influence of certain crystallographic orientations on plastic instability is shown.
