Identification of orthotropic plastic material parameters for deep-drawing steel using DIC and FEMU Schmaltz, Stefan; Willner, Kai (CIMNE, 2011)
Open AccessIn this paper the deep-drawing sheet steel DC04, representative for sheet-bulk metal forming processes, is characterized through uni- and biaxial tensile and compression tests. The orthotropic plastic material parameters ...
Schmaltz, Stefan; Willner, Kai (CIMNE, 2013)
Open AccessIn 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 ...
