| Popis: | In this paper an anisotropic material model at finite strain is implemented and utilised in a commercial Finite Element Software via a User-Subroutine. The material model is based on an additive split of the logarithmic strains to model the anisotropic finite strain behaviour of the material. The material parameters of the non-linear hardening and the orthotropic anisotropy are identified through an inverse Finite Element Model Updating procedure and verified with experimental testing. The chosen material is a sheet steel, which has a low initial yield strength and a high hardening capacity and therewith is typically used in deep-drawing and sheet-bulk metal forming processes. |
