摘要：

The heterogeneity coefficient described by surface roughness was introduced into Jalinier theory of computation of forming limit diagrams. The surface roughness is changed during sheet deformation, and in the same manner the heterogeneity coefficient is altered. Taking into account the changing of heterogeneity coefficient during forming of sheet resulted the better correlation between theory and experiments.
