| description | This paper presents a new parameter identification scheme for complex yield criteria of sheet metals using experimentally determined load and strain distributions and combining analytical stress analysis on sectional strain data with common inverse analysis. The approach is suitable for specimen with a non-homogenous strain distribution in the specimen and reduces computing time compared to common methods like iteratively updated FEM considerably. It serves to identify a set of material parameters in a fast and precise manner, describing the material behaviour. |
