“…The value deviations from the mean value lay within the standard deviation calculated. The finding complies to [16,17,18]. It is assumed, when the strain rate increases, the plastic deformation takes place in more slip planes, i.e.…”

The paper presents the findings of the strain rate effect, described in constitutive material models by strain rate sensitivity index m, to the strength and deformation material properties. These were evaluated from stress-strain diagrams recorded at tensile test using PC controlled testing machine TiraTEST 2300 according to STN EN ISO 6892-1. The high strength low alloyed steel H220PD, dual phase steel DP 600 and Trip steel RAK 40/70 were investigated at strain rates   = 0.0021, 0.083 and 0.125 s -1 . The results indicate major influence of the strain rate to the strength properties while only minor influence have been found when evaluate the deformation properties. The results also shown single phase materials are more sensitive to the strain rate than dual phase materials.

“…Jie et al (2009) conclude that for rate-dependent materials, a large discrepancy exists between the experimental FLD and FLD predicted using strain rate independent material properties. When the strain rate is taken into account, the studied AKDQ steel shows a higher FLD.…”

“…Chan [77] has developed a model of forming limits prediction for the superplastic forming. Predictive models of localized necking for strain-rate-dependent sheet metals have been developed by Mattiasson et al [209,210], Zhang et al [313], Jie et al [155]. The effect of the normal pressure on the formability of sheet metals is well known and has already been used in industry for a long time [161].…”

This paper presents synthetically the most recent models for description of the anisotropic plastic behavior. The first section gives an overview of the classical models. Further, the discussion is focused on the anisotropic formulations developed on the basis of the theories of linear transformations and tensor representations, respectively. Those models are applied to different types of materials: body centered, faced centered and hexagonalclose packed metals. A brief review of the experimental methods used for characterizing and modeling the anisotropic plastic behavior of metallic sheets and tubes under biaxial loading is presented together with the models and methods developed for predicting and establishing the limit strains. The capabilities of some commercial programs specially designed for the computation of forming limit curves (FLC) are also analyzed.
